SSC CHSL Tier 1 2016 General Intelligence & Reasoning Questions with Solutions

Explanation

The given series lists the Governors-General and Viceroys of India in chronological order of their terms of office. Warren Hastings served as the first Governor-General of Bengal from 1773 to 1785, which chronologically precedes Charles Cornwallis (1786 to 1793), Lord Dalhousie (1848 to 1856), Lord Canning (1856 to 1862), and Lord Curzon (1899 to 1905). This completes the chronological sequence of British administrators in India.

Explanation

The position values of the letters in the English alphabet are considered (A = 1, B = 2, ..., Z = 26).

For the first letter of each term, the differences between consecutive terms increase by 1 starting from 5: C (3) + 5 = H (8) H (8) + 6 = N (14) N (14) + 7 = U (21) U (21) + 8 = 29. Since there are 26 letters in the alphabet, 29 corresponds to 29 - 26 = 3, which is C.

For the second letter of each term, the same pattern of increasing differences is followed: D (4) + 5 = I (9) I (9) + 6 = O (15) O (15) + 7 = V (22) V (22) + 8 = 30. This corresponds to 30 - 26 = 4, which is D.

Combining these letters yields the next term in the series.

Explanation

The given series can be broken down into two alternating series of letters by using their alphabetical positions where A = 1, B = 2, and so on up to Z = 26.

For the first letter series, consisting of the first letter of Term 1, the first letter of Term 2, the third letter of Term 2, the first letter of Term 3, and the first letter of Term 4: I is 9 Q is 17, which is 9 + 8 X is 24, which is 17 + 7 D is 4, which is 30 in the cyclic alphabet, representing 24 + 6 The next value in this series is 30 + 5 = 35. In the cyclic alphabet, 35 - 26 = 9, which corresponds to the letter I.

For the second letter series, consisting of the second letter of Term 1, the second letter of Term 2, the fourth letter of Term 2, the second letter of Term 3, and the second letter of Term 4: B is 2 D is 4, which is 2 × 2 H is 8, which is 4 × 2 P is 16, which is 8 × 2 The next value in this series is 16 × 2 = 32. In the cyclic alphabet, 32 - 26 = 6, which corresponds to the letter F.

Combining the two letters obtained, I and F, yields the missing term IF.

Explanation

The series follows a pattern where consecutive multiples of 12 are added to each preceding term.

The differences between successive terms are: 25 - 13 = 12 (which is 12 × 1) 49 - 25 = 24 (which is 12 × 2) 85 - 49 = 36 (which is 12 × 3)

Following this sequence, the next difference must be the fourth multiple of 12, which is 48 (12 × 4).

Adding 48 to the last term of the series: 85 + 48 = 133

Explanation

To determine which conclusions follow, we analyze the relationship between the terms in the given statements.

Statement I tells us that all young scientists are open-minded. This means the group of young scientists is entirely contained within the group of open-minded people. It does not provide any information about scientists who are not young, nor does it cover all young people.

Statement II tells us that no open-minded men are superstitious. This restriction only applies to open-minded men, not to all open-minded people.

Looking at Conclusion I, which states that no scientist is superstitious, we cannot verify this because our statements only give information about young scientists. We know nothing about the superstition of other scientists, so this conclusion does not follow.

Looking at Conclusion II, which states that no young people are superstitious, we cannot verify this because our statements only refer to young scientists, which is a specific subset of young people. We have no information about young people who are not scientists, so this conclusion does not follow.

Therefore, neither conclusion follows.

Explanation

To determine the relative heights of the five friends, we can translate the given clues into inequality relationships.

The statement that Nishu is taller than Riya but shorter than Pooja gives: Pooja > Nishu > Riya

The statement that Riya is taller than Nikita extends this sequence to: Pooja > Nishu > Riya > Nikita

Since Amrita is the shortest, she is placed at the very end of the sequence: Pooja > Nishu > Riya > Nikita > Amrita

In this descending order of height, Pooja occupies the first position as the tallest, and Nishu occupies the second position.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare them letter by letter from left to right.

Comparing the third letters of all words, Apostate (iii) has o, whereas Apparent (i), Appointed (ii), and Apparel (iv) have p. Since o comes before p, Apostate (iii) is the first word in the sequence.

Comparing the fourth letters of the remaining three words, Apparent (i) and Apparel (iv) have a, while Appointed (ii) has o. Since a comes before o, Appointed (ii) must come after the other two.

Comparing the seventh letters of Apparel (iv) and Apparent (i) (since their first six letters are identical), Apparel has l and Apparent has n. Since l comes before n, Apparel (iv) precedes Apparent (i).

Explanation

By matching each letter in the words DELETE and GRAM to its corresponding symbol in their respective codes:

D corresponds to # E corresponds to @ L corresponds to T corresponds to % G corresponds to ! R corresponds to ? A corresponds to * M corresponds to | Using these letter-to-symbol mappings, the code for each letter in the word TELEGRAM is determined sequentially:

T becomes % E becomes @ L becomes E becomes @ G becomes ! R becomes ? A becomes * M becomes | Combining these symbols in order yields %@^@!?* | .

Explanation

The relationship in each column follows a multiplication pattern between the first two rows to obtain the number in the third row:

First Row Number × Second Row Number = Third Row Number

Let us verify this logic column by column:

For the second column: 31 × 17 = 527

For the first column: 99 × 15 = 1485

Note that 1485 is printed as 148 in the grid due to a minor typographical omission of the last digit.

Following the same logic for the third column: 91 × 18 = 1638

Explanation

Following the given operator substitutions, we replace the symbols with their corresponding mathematical operators: | represents division (÷) represents subtraction (-) @ represents addition (+) % represents multiplication (×)

Substituting these symbols into the expression 315 | 3#9@4%6 yields: 315 ÷ 3 - 9 + 4 × 6

Applying the BODMAS order of operations: First, perform the division: 315 ÷ 3 = 105

Next, perform the multiplication: 4 × 6 = 24

The expression now becomes: 105 - 9 + 24

Finally, solve the remaining operations from left to right: 105 - 9 + 24 = 96 + 24 = 120

Explanation

By placing the letters from option A (M, N, N, Q) in the given blanks, we get the following complete sequence:

MNMNOMNOPMNOPQ

When this sequence is broken down into parts, a clear pattern of progressively growing alphabetical strings emerges:

MN / MNO / MNOP / MNOPQ

In each successive block, the sequence starts from the letter M and one additional consecutive letter of the alphabet is appended to the end. Thus, the filled letters that complete this pattern are M, N, N, and Q in order.

Explanation

Initially, Navjot is moving towards the West. When he turns left, he rotates 90 degrees counter-clockwise, which changes his direction of movement to the South. From the South direction, taking a right turn means rotating 90 degrees clockwise, which brings his direction back to the West. He is currently facing West.

Explanation

The word NORM can be successfully identified using the codes in option a as follows. For the letter N, row 4 and column 4 of Matrix-I intersect at N, which gives the code 44. For the letter O, row 0 and column 4 of Matrix-I intersect at O, giving the code 04. For the letter R, row 5 and column 8 of Matrix-II intersect at R, which gives the code 58. For the letter M, row 8 and column 6 of Matrix-II intersect at M, giving the code 86. Putting these codes together in order gives 44, 04, 58, 86.

Explanation

Identify the relation step-by-step from the girl's perspective. The girl refers to the only child of her father-in-law. Her father-in-law is her husband's father. Since this father-in-law has only one child, that child must be her husband. The statement then simplifies to saying that the woman is the mother of the girl's husband. The mother of a person's husband is their mother-in-law.

Explanation

The given relationship associates an international airport with the city in which it is located. Rajiv Gandhi International Airport is located in Hyderabad. Similarly, Indira Gandhi International Airport is located in Delhi.

Explanation

The relationship between the first pair of letter groups is determined by subtracting 4 from the alphabetical position of each letter in the first group to obtain the corresponding letter in the second group.

Using the alphabetical positions: T (20) - 4 = P (16) E (5) - 4 = A (1) W (23) - 4 = S (19)

Applying the same pattern to IVX: I (9) - 4 = E (5) V (22) - 4 = R (18) X (24) - 4 = T (20)

This gives the letter group ERT.

Explanation

The relationship between the letters of the first pair follows an increasing addition pattern of consecutive integers:

P + 1 = Q E + 2 = G O + 3 = R N + 4 = R

Applying this same pattern to the word RUDE:

R + 1 = S U + 2 = W D + 3 = G E + 4 = I

Explanation

The relationship between the first and second terms is established by multiplying the second and third digits of the number and then adding the first digit to the product.

For 167 : 43, the calculation is 1 + (6 × 7) = 1 + 42 = 43.

Applying the same logic to 245: 2 + (4 × 5) = 2 + 20 = 22.

Explanation

Transparent represents a state of complete clarity that allows light to pass through fully without any scattering or obstruction, making objects on the other side perfectly visible. This is the only term that denotes absolute clarity and unobstructed transmission of light, distinguishing it from terms that denote varying degrees of opacity, scattering, or obstruction to light.

Explanation

The letter combination REE follows a consonant-vowel-vowel pattern, consisting of a single consonant followed by two identical vowels. All other combinations in the group follow a vowel-consonant-consonant pattern, consisting of a single vowel followed by two identical consonants.

Explanation

The sum of the first and the third digits in three of the given numbers equals the middle digit, such as 2 + 6 = 8, 3 + 4 = 7, and 1 + 3 = 4. For 279, the sum of the first and third digits is 2 + 9 = 11, which is not equal to the middle digit 7. Additionally, 279 is not divisible by 11, whereas the other three numbers are completely divisible by 11.

Explanation

The numbers 358, 853, and 538 are all permutations of the same three digits: 3, 5, and 8. The number 240 is formed by a completely different set of digits (2, 4, and 0).

Additionally, for the first three numbers, the sum of two of the digits equals the remaining digit (3 + 5 = 8), a pattern that does not hold for 240.

Explanation

The terms in the given series represent successive place values in the Indian numbering system. Starting from Thousand, each subsequent term increases by a factor of ten.

Thousand represents 1,000. Ten thousand represents 10,000. Lakh represents 100,000. Ten lakh represents 1,000,000.

Following this established sequence, multiplying the previous value of Ten lakh by ten yields 10,000,000, which corresponds directly to Crore in the Indian numbering system.

Explanation

The series follows a pattern where the alphabetical position of each letter in a term is multiplied by 2 to get the corresponding letter of the next term.

For the first letters of each term, the alphabetical positions are A (1), B (2), and D (4). Multiplying the position of D (4) by 2 gives 8, which corresponds to H.

For the second letters of each term, the positions are B (2), D (4), and H (8). Multiplying the position of H (8) by 2 gives 16, which corresponds to P.

For the third letters of each term, the positions are C (3), F (6), and L (12). Multiplying the position of L (12) by 2 gives 24, which corresponds to X.

Combining these letters yields HPX.

Explanation

The letters of each term are consecutive in the English alphabet, and the series progresses by increasing the gap between consecutive terms.

By analyzing the numerical positions of the first letters of each term: I = 9 P = 16 (9 + 7) X = 24 (16 + 8)

Following the pattern of adding consecutive integers (+7, +8, +9), the next first letter is obtained by adding 9 to 24: 24 + 9 = 33 In the 26-letter cyclical alphabet, 33 corresponds to 33 - 26 = 7, which is G.

Similarly, analyzing the second letters of each term: J = 10 Q = 17 (10 + 7) Y = 25 (17 + 8)

Adding 9 to the position of Y gives the next second letter: 25 + 9 = 34 In the cyclical alphabet, 34 corresponds to 34 - 26 = 8, which is H.

Explanation

The series follows the pattern where each subsequent term is obtained by multiplying the previous term by an increasing integer and then adding that same integer, starting with 2.

For the first transition: 15 × 2 + 2 = 32 For the second transition: 32 × 3 + 3 = 99 For the third transition: 99 × 4 + 4 = 400 For the fourth transition: 400 × 5 + 5 = 2005

Explanation

Using the rules of set theory and syllogisms, we can analyze the statements as follows:

Let H represent horses, B represent bullocks, and G represent goats.

The first statement, All horses are bullocks, means that the set of horses is a subset of bullocks: H ⊆ B

The second statement, All bullocks are goats, means that the set of bullocks is a subset of goats: B ⊆ G

By the transitive property of subset inclusion, if H is a subset of B and B is a subset of G, then H must be a subset of G: H ⊆ G

This means that all horses are goats, which perfectly validates Conclusion I.

Explanation

We can establish the order of speed from fastest to slowest based on the given clues.

First, the deer was the fastest, placing it in 1st position.

Second, the dog ran faster than the elephant but slower than the tiger, giving the relative order: Tiger > Dog > Elephant.

Third, the lion ran faster than the tiger, which extends the relative order to: Lion > Tiger > Dog > Elephant.

Combining all information from fastest to slowest, the order of finishing is: Deer > Lion > Tiger > Dog > Elephant.

This places the lion in the 2nd position.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare them letter by letter from left to right.

All four words begin with the letter C. Looking at the second letters: Cajole has a. Clandestine has l. Cover and Coward both have o.

Since a comes before l, and l comes before o in the English alphabet, Cajole (iv) is first, followed by Clandestine (ii).

To determine the order between Cover (i) and Coward (iii), we compare their third letters because their first two letters, c and o, are identical. In Cover, the third letter is v, and in Coward, the third letter is w. Since v comes before w, Cover (i) precedes Coward (iii).

Combining these positions gives the final sequence: Cajole (iv), Clandestine (ii), Cover (i), Coward (iii).

Explanation

By comparing the word NIGERIA with its code, each letter is assigned a specific symbol:

N is represented by @ I is represented by # G is represented by E is represented by R is represented by ? A is represented by *

Using this direct letter-to-symbol substitution, the word GINGER is coded as follows:

G is replaced by I is replaced by # N is replaced by @ G is replaced by E is replaced by R is replaced by ?

Putting the symbols together in sequence, the code for GINGER is ^#@^?.

Explanation

The sum of the numbers in each column remains constant and is equal to 155.

For the first column: 45 + 50 + 60 = 155

For the second column: 55 + 51 + 49 = 155

Following the same logic for the third column: 26 + 65 + ? = 155 91 + ? = 155 ? = 155 - 91 = 64

Explanation

Replacing the mathematical signs according to the given instructions:

• is replaced by - x is replaced by ÷ is replaced by + ÷ is replaced by ×

The given expression is: 26 + 400 x 20 - 21 ÷ 12

After substituting the signs, the expression becomes: 26 - 400 ÷ 20 + 21 × 12

Using the BODMAS rule, perform the operations in order:

First, solve the division: 400 ÷ 20 = 20 Which simplifies the expression to: 26 - 20 + 21 × 12

Next, solve the multiplication: 21 × 12 = 252 Which simplifies the expression to: 26 - 20 + 252

Finally, perform the addition and subtraction: 6 + 252 = 258

Explanation

By sequentially placing the letters A, A, A, and B from option B into the gaps of the series _BA_BBA_AB_B, we obtain the completed sequence:

ABAABBAAABBB

This sequence forms a distinct, repeating pattern of increasing length:

AB, AABB, AAABBB

The pattern consists of a group of A's followed by an equal number of B's, with the count of each letter increasing by one in each subsequent group. This completes the logical progression of the series.

Explanation

To find the distance between the initial and final positions, we can track the cat's movement on a coordinate system starting at (0, 0).

First, the cat moves 25m North, reaching the coordinates (0, 25).

Next, it turns right (East) and moves 100m, reaching (100, 25).

Then, it turns South and moves 25m, which brings its vertical position back to the starting level, reaching (100, 0).

Finally, while facing South, it turns left (East) and moves 55m, ending at (155, 0).

Since the final vertical position is the same as the starting vertical position, the straight-line distance is purely horizontal and is calculated as 100 + 55 = 155m.

Explanation

The letters of the word FIRED are represented by identifying their row index followed by their column index from the respective matrices:

F is located at Row 6, Column 8 in Matrix-II, giving 68. I is located at Row 6, Column 6 in Matrix-II, giving 66. R is located at Row 1, Column 4 in Matrix-I, giving 14. E is located at Row 2, Column 4 in Matrix-I, giving 24. D is located at Row 0, Column 1 in Matrix-I, giving 01.

This yields the complete code set: 68, 66, 14, 24, 01.

Explanation

We can break down the statement made by Poonam step-by-step to find the relationship:

First, the son of Poonam's mother refers to Poonam's brother.

Second, the only sister of Poonam's brother must be Poonam herself.

Third, the daughter of Poonam is the girl being introduced.

Therefore, the girl is Poonam's daughter.

Explanation

Sardar Vallabhbhai Patel is popularly known as the Iron Man of India for his monumental role in integrating over five hundred princely states into the Indian Union. In the same manner, Mahatma Gandhi is revered as the Father of the Nation for leading India to independence from British colonial rule through his philosophy of non-violence and satyagraha.

Explanation

The letters of the word are divided into three parts: the first three letters, the middle letter, and the last three letters.

In GLIDERS: First three letters: GLI Middle letter: D Last three letters: ERS

The pattern rearranges the word by placing the last three letters first, followed by the middle letter, and then the first three letters. Thus, GLIDERS becomes ERSDGLI.

Applying the same positional rearrangement to TOASTER: First three letters: TOA Middle letter: S Last three letters: TER

Placing the last three letters (TER), followed by the middle letter (S), and then the first three letters (TOA) results in TERSTOA.

Explanation

The relationship is based on reversing the letters of the word in specific groups. The seven-letter word is split into three parts: the first three letters, the middle single letter, and the last three letters. The first three letters are reversed, the middle letter remains in its position, and the last three letters are reversed.

For THUNDER, it is split into THU, N, and DER. Reversing the first and last parts and keeping the middle part as it is gives UHT, N, and RED, which combines to form UHTNRED.

Applying the same pattern to THIEVES, it is split into THI, E, and VES. Reversing the first and last parts gives IHT, E, and SEV, which combines to form IHTESEV.

Explanation

The logic followed in this analogy is adding 111 to the first number to obtain the second number, which is equivalent to increasing each individual digit of the three-digit number by 1.

For the first pair: 534 + 111 = 645

Applying the same logic to the second pair: 381 + 111 = 492

This increases the digits 3, 8, and 1 by 1 to become 4, 9, and 2 respectively.

Explanation

Mustard gas is a highly toxic, blister-inducing chemical weapon and cytotoxic warfare agent that is used exclusively in military conflict. Unlike the other substances which are common fossil fuels used to generate power and run vehicles, mustard gas is not a fuel and has no energy production applications, making it the odd one out in the group.

Explanation

By converting the alphabetical positions of the letters into numbers, we find: P = 16, D = 4 I = 9, C = 3 D = 4, B = 2

In these pairs, the numerical position of the first letter is the square of the position of the second letter (x = y²).

For the pair LE, the numerical positions are L = 12 and E = 5. Since 12 is not the square of 5, this pair does not follow the established rule of the other pairs, making it the odd one out.

Explanation

To find the odd one out, we analyze the mathematical properties of the numbers. The number 1321 is not a perfect cube of any integer. In contrast, the other numbers are perfect cubes of integers, representing 5³ = 125, 8³ = 512, and 12³ = 1728. The closest perfect cube to 1321 is 11³ which equals 1331, making 1321 structurally different from the rest.

Explanation

The sum of the digits of the numbers 125, 512, and 1331 is equal to 8, as shown below: 1 + 2 + 5 = 8 5 + 1 + 2 = 8 1 + 3 + 3 + 1 = 8

For the number 1728, the sum of the digits is: 1 + 7 + 2 + 8 = 18

This makes 1728 the odd number in the group because its digit sum is 18 instead of 8.

Explanation

The given series is arranged in descending order of the ages of prominent Indian nationalist leaders, which corresponds to the chronological order of their birth years:

Dadabhai Naoroji: Born on 4 September 1825 Bal Gangadhar Tilak: Born on 23 July 1856 Lala Lajpat Rai: Born on 28 January 1865 Mahatma Gandhi: Born on 2 October 1869

Since Mahatma Gandhi has the next successive birth year following Lala Lajpat Rai, he completes the series.

Explanation

The series follows a pattern where the first and second letters of each term increment by specific constant values based on their positions in the alphabetical order (A = 1, B = 2, ..., Z = 26).

For the first letter of each term, the positions increase by 4: H (8) + 4 = L (12) L (12) + 4 = P (16) P (16) + 4 = T (20) T (20) + 4 = X (24)

For the second letter of each term, the positions increase by 3: K (11) + 3 = N (14) N (14) + 3 = Q (17) Q (17) + 3 = T (20) T (20) + 3 = W (23)

Combining the two letters gives the missing term LN.

Explanation

The series follows a specific increment pattern in the alphabetical positions of both the first and second letters of each term.

For the first letter of each pair: J (10) + 5 = O (15) O (15) + 6 = U (21) U (21) + 7 = B (28, which is 2) B (2) + 8 = J (10)

For the second letter of each pair: N (14) + 4 = R (18) R (18) + 5 = W (23) W (23) + 6 = C (29, which is 3) C (3) + 7 = J (10)

Combining the two resulting letters gives JJ.

Explanation

The pattern of the series involves multiplying each term by a consecutive integer and then adding that same integer to the product.

The terms are generated as follows:

First term = 30 Second term = 30 × 2 + 2 = 62 Third term = 62 × 3 + 3 = 189 Fourth term = 189 × 4 + 4 = 760 Fifth term = 760 × 5 + 5 = 3805

Explanation

According to the first statement, holding a first division is the condition required for admission. Since the second statement confirms that Ram is a first division holder, he fulfills this criterion, which leads to the conclusion that Ram is admitted. Therefore, Conclusion I logically follows.

Explanation

Let the positions of the five friends from left to right be represented from 1 to 5, facing north.

Ankit is sitting to the immediate right of Anjum, which gives the pair Anjum - Ankit.

Ram is sitting to the right of Ankit, placing Ram to the right of the Anjum - Ankit pair.

Amit is sitting to the immediate right of Ram, which forms the sequence Ram - Amit.

Amit is also sitting to the left of Priya, which means Priya must be placed to the right of Amit.

Combining all these conditions gives the unique sequence from left to right as Anjum, Ankit, Ram, Amit, Priya, placing Priya at the extreme right end.
