Explanation

Representing the statements using sets: Lions are entirely contained within Monkeys, Monkeys and Cats have a partial overlap, and Pigs are entirely contained within Cats.

Since Pigs are located inside the set of Cats, and Cats only partially overlap with Monkeys, Pigs do not necessarily overlap with Monkeys. Furthermore, Lions are a subset of Monkeys, so there is no definite relation established between Pigs and Lions.

Since neither relation is guaranteed to hold true in all possible Venn diagram representations, neither conclusion (I) nor (II) logically follows.

Explanation

Interchanging ÷ with × and + with - in the expression gives:

216 × 3 - 1313 ÷ 13 + 112

Applying the BODMAS rule:

Division: 1313 ÷ 13 = 101 Multiplication: 216 × 3 = 648 Subtraction and Addition: 648 - 101 + 112 = 547 + 112 = 659

Explanation

To find symbols that are immediately preceded by another symbol and immediately followed by a number, we look for the pattern Symbol - Symbol - Number in the series.

Scanning from left to right through the series: In the group ? % 4, the symbol % is preceded by symbol ? and followed by number 4. In the group > 2, the symbol > is preceded by symbol and followed by number 2.

There are 2 such symbols (% and >) that satisfy both conditions.

Explanation

Decoding the given expression step by step:

P + Q means P is the husband of Q. Q - R means Q is the mother of R, which implies P is the father of R. R × S means R is the wife of S, so R is female. S + T means S is the father of T, which implies R is the mother of T.

Since P is the father of R and R is the mother of T, P is the father of T's mother (mother's father).

Explanation

In the given sets, the numbers form an arithmetic progression with a common difference of +2: 5 + 2 = 7 and 7 + 2 = 9 11 + 2 = 13 and 13 + 2 = 15

Similarly, the set 21- 23- 25 follows the exact same logic: 21 + 2 = 23 and 23 + 2 = 25

Explanation

The pattern followed in each set (A, B, C) is B = A² + (C - 1).

In the first set (24, 578, 3): 24² + (3 - 1) = 576 + 2 = 578

In the second set (23, 536, 8): 23² + (8 - 1) = 529 + 7 = 536

Applying this pattern to (10, 106, 7): 10² + (7 - 1) = 100 + 6 = 106

Explanation

The pattern follows an alternating addition to the alphabetical positions of the letters: +2 for the first and third letters, and +3 for the second and fourth letters.

For GKOS to INQV: G (7) + 2 = I (9) K (11) + 3 = N (14) O (15) + 2 = Q (17) S (19) + 3 = V (22)

For HLPT to JORW: H (8) + 2 = J (10) L (12) + 3 = O (15) P (16) + 2 = R (18) T (20) + 3 = W (23)

Applying the same rule to AEIM: A (1) + 2 = C (3) E (5) + 3 = H (8) I (9) + 2 = K (11) M (13) + 3 = P (16)

Explanation

Placing the 7 seats in clockwise order (1 to 7), where clockwise corresponds to left and counter-clockwise corresponds to right:

S is placed at position 1. Since M sits 4th to the right (counter-clockwise) of S, M is at position 4.

The remaining unoccupied seats are 2, 3, 5, 6, and 7. Since N is an immediate neighbour of both O and Q, the group {O, N, Q} must occupy the only contiguous three-seat block available, which is positions 5, 6, and 7, placing N at position 6.

Counting left (clockwise) from P, there are two people between P and Q. This places Q at position 5, P at position 2, and the remaining person R at position 3. Position 7 is occupied by O, which correctly makes R (position 3) 3rd to the left of O.

The complete clockwise seating order from position 1 to 7 is S, P, R, M, Q, N, O.

Counting from the left (clockwise) of N (position 6) to reach M (position 4), the people sitting between them are O (position 7), S (position 1), P (position 2), and R (position 3), making a total of four people.

Explanation

K lives on an odd-numbered floor other than 3, so K is on floor 1 or 5. Since J lives immediately below K, K cannot be on floor 1. Thus, K lives on floor 5 and J lives on floor 4.

Two people live between K (floor 5) and L, placing L on floor 2. M lives on an even-numbered floor, which leaves floor 6 for M as floors 2 and 4 are occupied. Since O does not live on floor 1, O lives on floor 3 and N lives on floor 1.

N is on floor 1 and J is on floor 4. The two people living between them are L (floor 2) and O (floor 3).

Explanation

The standard pattern in the group follows a positional increment of +4 and +5 between consecutive letters in the English alphabet. For FJN, the positional values are F (6), J (10), and N (14), which follows an increment pattern of +4 and +4 instead of +4, +5.

Explanation

The pattern followed in each pair is adding 7 to the alphabetical position of each letter.

For the left pair, EHN : LOU: E (5) + 7 = 12 (L) H (8) + 7 = 15 (O) N (14) + 7 = 21 (U)

For the right pair, WZF : DGM: W (23) + 7 = 30 ≡ 4 (D) Z (26) + 7 = 33 ≡ 7 (G) F (6) + 7 = 13 (M)

Replacing # with EHN and % with DGM completes the analogy.

Explanation

Facing the centre of the circular table, clockwise represents the left direction and counter-clockwise represents the right direction.

Fixing position 1 for F: H sits 3rd to the left of F, placing H at position 4. Only F sits between G and I, so G and I occupy positions 2 and 7. I sits 2nd to the left of V. Placing I at position 7 puts V at position 5. Placing I at position 2 would require V to be at position 7, which is occupied by G, so I is at position 7 and G is at position 2. The remaining positions for W and X are 3 and 6. Since W cannot sit next to H (position 4), W sits at position 6 and X sits at position 3.

The clockwise order around the table is: F (1), G (2), X (3), H (4), V (5), W (6), I (7).

Counting to the right (counter-clockwise) of X at position 3 towards I at position 7, the people sitting in between are G and F, making a total of two people.

Explanation

Comparing the two words 'GLOW' and 'WEAR', the only letter common to both is 'W'. Similarly, comparing their respective numerical codes '4628' and '3574', the only digit common to both is '4'. Therefore, the code for the letter 'W' is 4.

Explanation

The series follows two distinct patterns for the letter clusters and the numbers:

For the letter clusters, each positional letter decreases by 2 in alphabetical position (wrapping around from A to Z): First letter: H(8) - 2 = F(6), F(6) - 2 = D(4), D(4) - 2 = B(2), B(2) - 2 = Z(26) Second letter: G(7) - 2 = E(5), E(5) - 2 = C(3), C(3) - 2 = A(1), A(1) - 2 = Y(25) Third letter: H(8) - 2 = F(6), F(6) - 2 = D(4), D(4) - 2 = B(2), B(2) - 2 = Z(26) This gives the letter cluster ZYZ.

For the numbers, each value decreases by 11: 85 - 11 = 74 74 - 11 = 63 63 - 11 = 52 52 - 11 = 41

Combining both gives the next cluster ZYZ 41.

Explanation

The relationship between the letter-clusters is based on moving each letter one position backward (-1) in alphabetical order.

For the left pair, replacing # with SXV gives Rwu: S - 1 = R X - 1 = W (w) V - 1 = U (u)

Applying the same pattern to the right pair KPN: K - 1 = J P - 1 = O N - 1 = M

Explanation

The standard pattern followed by the group adds 7 to the position of the first letter to get the second letter, and subtracts 4 from the second letter to get the third letter. In PWR, P is the 16th letter, W is the 23rd letter (16 + 7 = 23), and R is the 18th letter (23 - 5 = 18). Because the shift between the second and third letters is -5 instead of -4, it does not belong to the group.

Explanation

Replacing the letters with their corresponding mathematical operators (A = ÷, B = ×, C = +, D = -) gives the equation:

22 ÷ 2 × 1 + 3 - 2

Applying the BODMAS rule: Division: 22 ÷ 2 = 11 Multiplication: 11 × 1 = 11 Addition: 11 + 3 = 14 Subtraction: 14 - 2 = 12

Explanation

The logic behind the given pairs is a progressive addition of +1, +2, and +3 to the alphabetical positions of the first, second, and third letters respectively.

In AOE : BQH, A + 1 = B, O + 2 = Q, and E + 3 = H. In OST : PUW, O + 1 = P, S + 2 = U, and T + 3 = W.

Applying the exact same rule to SHF gives S + 1 = T, H + 2 = J, and F + 3 = I, resulting in TJI.

Explanation

Comparing the words LITE and FELT, the common letters are L, E, and T, which correspond to the common digits 8, 1, and 6 in their respective codes (8196 and 6481). The only remaining letter in FELT is F, and the only remaining digit in its code is 4. Thus, F is coded as 4.

Explanation

The given statements establish a continuous chain of subset inclusions: Coppers ⊂ Irons ⊂ Silvers ⊂ Golds.

Since all irons belong to golds (Irons ⊂ Silvers ⊂ Golds), it directly follows that some golds are irons, making conclusion (I) valid.

Conversely, since coppers form a subset inside silvers, it does not guarantee that all silvers are coppers, so conclusion (II) does not logically follow.

Explanation

Placing the exams day-by-day based on the given statements gives the complete schedule:

Tuesday is fixed for T.

Since two people have exams between R and T, R must have the exam on Friday.

P has the exam immediately after S, forming an consecutive pair (S, P). Since P cannot be on Sunday and Tuesday/Friday are occupied, S and P must be on Wednesday and Thursday respectively.

Q has the exam before V and not on Monday, which places Q on Saturday and V on Sunday. The remaining person, U, must have the exam on Monday.

The final sequence from Monday to Sunday is U, T, S, P, R, Q, V.

Between U (Monday) and P (Thursday), there are two people (T and S).

Explanation

Using Point D as the origin (0, 0): Movement 1: 5 km South gives displacement (0, -5). Movement 2: Turning left (East) and walking 9 km gives displacement (9, -5). Movement 3: Turning left (North) and walking 5 km gives displacement (9, 0). Movement 4: Turning right (East) and walking 2 km gives displacement (11, 0).

The net vertical displacement is -5 + 5 = 0 km, and the net horizontal displacement is 9 + 2 = 11 km towards East.

Explanation

The series follows a dual pattern where each letter advances by 4 positions in the alphabetical order, while the number increases by 3 in each step:

First letter: M (13) + 4 = Q (17), Q (17) + 4 = U (21), U (21) + 4 = Y (25), Y (25) + 4 = C (3)

Second letter: R (18) + 4 = V (22), V (22) + 4 = Z (26), Z (26) + 4 = D (4), D (4) + 4 = H (8)

Third letter: A (1) + 4 = E (5), E (5) + 4 = I (9), I (9) + 4 = M (13), M (13) + 4 = Q (17)

Number: 17 + 3 = 20, 20 + 3 = 23, 23 + 3 = 26, 26 + 3 = 29

Combining these yields CHQ 29.

Explanation

The pattern in the series involves subtracting consecutive prime numbers from each term:

65 - 2 = 63 63 - 3 = 60 60 - 5 = 55 55 - 7 = 48

The prime numbers subtracted in order are 2, 3, 5, and 7. The next prime number is 11.

Subtracting 11 from 48 gives: 48 - 11 = 37

Explanation

Dropping all letters (J, M, L, G, F, W, D, B, H, N) from the series leaves only the sequence of symbols: * % # @ @ # ? + %.

Counting these symbols from right to left gives % as the 1st, + as the 2nd, ? as the 3rd, # as the 4th, @ as the 5th, @ as the 6th, and # as the 7th symbol from the right.

Explanation

Since S is the mother of N and N is the sister of U, S is also the mother of U. E is married to U as her husband, which makes U the wife of E. Therefore, S is the wife's mother of E.

Explanation

Given number: 5714623

Applying the transformation rules: 5 (odd) + 1 = 6 7 (odd) + 1 = 8 1 (odd) + 1 = 2 4 (even) - 2 = 2 6 (even) - 2 = 4 2 (even) - 2 = 0 3 (odd) + 1 = 4

The transformed number is 6822404.

The digit second from the left is 8, and the digit second from the right is 0.

Sum = 8 + 0 = 8

Explanation

The pattern followed in the given sets is: Second number = (3 × First number) + Third number - 2

For (40, 122, 4): (3 × 40) + 4 - 2 = 120 + 2 = 122

For (30, 101, 13): (3 × 30) + 13 - 2 = 90 + 11 = 101

Similarly, for (37, 120, 11): (3 × 37) + 11 - 2 = 111 + 9 = 120

Explanation

The pattern followed by the numbers in each set (a, b, c) is (a × b) - 5 = c.

First set: (15 × 7) - 5 = 105 - 5 = 100 Second set: (25 × 8) - 5 = 200 - 5 = 195

Applying the same relation to (23, 6, 133): (23 × 6) - 5 = 138 - 5 = 133

Explanation

In the standard pattern followed by the group, the letters within each cluster have a positional difference of +3, and the two clusters are separated by a gap of +2 positions. In LO- PV, while L (12) + 3 = O (15), the gap from O (15) to P (16) is +1 and the difference between P (16) and V (22) is +6, failing to follow the +3, +2, +3 pattern.

Explanation

From the given statements, kites are a subset of rabbits, eagles are completely separate from kites, and all eagles are inside the set of pigs.

For conclusion (I), while eagles (which are pigs) cannot be kites, there is no restriction preventing pigs from overlapping with or containing rabbits. Thus, "No pig is a rabbit" is not definitely true.

For conclusion (II), eagles cannot be kites, but non-eagle pigs may or may not overlap with kites, as no statement guarantees a common region between pigs and kites. Thus, "Some pigs are kites" does not necessarily follow.

Explanation

The pattern of operations across the numbers in each set is: 1st number + 10 = 2nd number 2nd number × 2 = 3rd number 3rd number + 20 = 4th number

Applying this rule to the given sets: Set 1: 8 + 10 = 18, 18 × 2 = 36, 36 + 20 = 56 Set 2: 12 + 10 = 22, 22 × 2 = 44, 44 + 20 = 64

Applying the same operations to 20 – 30 – 60 – 80: 20 + 10 = 30 30 × 2 = 60 60 + 20 = 80

Explanation

Statement I gives the age relation Sandeep > Mohit > Kunal, omitting Rohan and Tarun. Statement II gives the relation Sandeep > Tarun > Mohit, omitting Rohan and Kunal. Combining both statements establishes that Sandeep is older than Tarun, Mohit, and Kunal (Sandeep > Tarun > Mohit > Kunal). However, neither statement provides any information regarding Rohan's age. Since Rohan could potentially be older than Sandeep, the oldest person cannot be uniquely determined even after combining both statements.

Explanation

Arranging seven people around a circular table facing the centre, clockwise movement corresponds to left and anticlockwise movement corresponds to right.

Placing F at a reference position and counting to its right (anticlockwise), two seats are left empty before placing B. Counting to the left (clockwise) from A, two seats lie between A and B, which positions A two seats before B.

Counting three positions to the right (anticlockwise) from F places C. Since E sits to the immediate left (clockwise) of D, placing D and E into adjacent seats leaves the last remaining seat for G.

The complete circular arrangement in clockwise order is F, A, G, C, B, D, E. Counting from the right of A (anticlockwise), only F sits between A and E, so the number of people between them is 1.

Explanation

Dropping all the numbers (3, 6, 8, 2, 7, 3) from the given series leaves the sequence of non-digit characters from left to right:

D, T, E, Z, %, U, P, *, @, J, V, @, H, N

Counting the non-digit characters from the left: 1st: D 2nd: T 3rd: E 4th: Z 5th: %

Explanation

Lalit is flanked by Kamal above and Manish below, forming a consecutive three-floor block (Kamal, Lalit, Manish) with Lalit on an even floor. If Lalit were on floor 2, the block would occupy floors 3, 2, 1. To place Pawan on an even floor immediately above Neil, Pawan and Neil would have to take floors 6 and 5 respectively, leaving Om on floor 4, which violates the condition that Om cannot live on floor 4.

Thus, Lalit lives on floor 4, placing Kamal on floor 5 and Manish on floor 3. Pawan lives on an even floor immediately above Neil, placing Pawan on floor 2 and Neil on floor 1. The only remaining floor for Om is floor 6.

Explanation

Each letter in the given sequence is shifted forward in the English alphabetical order by positional increments of +3, +4, +4, and +3 respectively.

Applying this pattern: GJHA → G(+3) J(+4) H(+4) A(+3) → JNLD KMEL → K(+3) M(+4) E(+4) L(+3) → NQIO

Applying the same logic to NROT: N (+3) = Q R (+4) = V O (+4) = S T (+3) = W

This gives the pattern QVSW.

Explanation

The difference between consecutive terms follows the sequence of consecutive prime numbers:

11 - 9 = 2 14 - 11 = 3 19 - 14 = 5 26 - 19 = 7

The next prime number after 7 is 11. Adding 11 to the last term gives 26 + 11 = 37.

Explanation

Mapping the days sequentially from Monday to Sunday:

C's meeting is fixed on Thursday.

Since one person sits between C and F, F must be on Saturday because placing F on Tuesday would force A onto Monday, which is disallowed. Consequently, A's meeting is on Friday and F's is on Saturday.

With two persons between A and G, G's meeting falls on Tuesday.

The remaining open days are Monday, Wednesday, and Sunday. Arranging D, B, and E such that B is after D and before E places D on Monday, B on Wednesday, and E on Sunday.

Explanation

To satisfy the given condition, a symbol must follow the pattern: Number - Symbol - Number.

Scanning the sequence from left to right: Ω % + # 3 ? = ε 1 4 9 2 6 5 @ 7 8

The only element matching this pattern is @ in 5 @ 7, where the symbol @ is immediately preceded by the single-digit number 5 and immediately followed by the single-digit number 7. No other symbol meets both conditions simultaneously.

Explanation

Under Section 45ZA of the Reserve Bank of India (RBI) Act, 1934, the Government of India, in consultation with the RBI, determines the Consumer Price Index (CPI) inflation target once every five years. For the five-year period spanning from April 1, 2021, to March 31, 2026, the flexible inflation targeting framework retains the target of 4% with a tolerance band of ±2%, maintaining an acceptable inflation range of 2% to 6%.

Explanation

Replacing the letters with their corresponding mathematical operators: A = + B = × C = + D = –

Substituting these into the given expression: 13 B 2 C 6 D 8 A 4 = 13 × 2 + 6 – 8 + 4

Following the BODMAS rule for order of operations: 13 × 2 = 26 26 + 6 – 8 + 4 = 32 – 8 + 4 = 28

Explanation

In the pair OR-OU, shifting each letter of the first cluster (OR) forward by one position (+1) in the English alphabetical order yields PS instead of OU, as O shifts by +0 to become O and R shifts by +3 to become U. This deviates from the uniform +1 shift applied to both letters in the standard pattern.

Explanation

Among the given numbers (442, 405, 297, 384, and 316):

The highest number is 442, whose third digit is 2. The lowest number is 297, whose second digit is 9.

Summing the two digits gives 2 + 9 = 11.

Explanation

Thermal pollution occurs when industrial facilities, such as thermal power plants, nuclear reactors, and manufacturing units, withdraw water from natural sources like rivers, lakes, or oceans to use as a cooling agent. After absorbing waste heat generated during manufacturing or power generation processes, this warm water is discharged back into the natural water bodies, significantly raising ambient water temperatures and decreasing dissolved oxygen levels required by aquatic organisms.

Explanation

The pattern followed is: Second number = (First number × 3) - 6

Applying this rule to the given numbers: 22 × 3 - 6 = 66 - 6 = 60 27 × 3 - 6 = 81 - 6 = 75

Applying the same rule to 33: 33 × 3 - 6 = 99 - 6 = 93

Explanation

20% of 620 = 0.2 × 620 = 124.

According to the question, 20% of the number is 200 more than 124: 20% of x = 124 + 200 = 324

Multiplying both sides by 5: x = 324 × 5 = 1620.

Explanation

Since all hands are legs and some hands are faces, the hands that are faces are automatically legs as well, which means some legs are faces. Therefore, conclusion (I) logically follows. Conclusion (II) does not follow because combining two particular premises (some hands are faces and some faces are arms) gives no definite relation between hands and arms.

Explanation

Each term in the series decreases progressively in both its alphabetical and numerical components.

For the letters, each letter shifts backward by 1 position in alphabetical order, wrapping around from A to Z: the first letter sequence is D → C → B → A → Z; the second letter sequence is H → G → F → E → D; and the third letter sequence is G → F → E → D → C.

For the numbers, each term decreases by 4: 42 → 38 → 34 → 30 → 26.

Combining these patterns gives the cluster ZDC 26.

Explanation

Number the seven positions from 1 to 7 from left to right.

Since only two people sit to the left of C, C is at position 3.

Only three people sit between C and F, which places F at position 7.

B sits second to the right of C, placing B at position 5.

Only two people sit between B and D, so D must be at position 2.

The remaining open positions are 1, 4, and 6. Placing E to the right of G and to the left of A gives G at position 1, E at position 4, and A at position 6.

The final order from left to right is G, D, C, E, B, A, F. Only G sits to the left of D, making a total of 1 person to the left of D.
