IBPS RRB Clerk Prelims 2016 Reasoning Questions with Solutions

Explanation

Since all bottles are contained within mugs and no mug is a cup, no bottle can overlap with cups, making Conclusion I definitely true. Furthermore, because all bottles are mugs, it directly implies that at least some mugs are bottles, making Conclusion II definitely true as well.

Explanation

All entrances are contained inside windows, which are in turn contained inside doors. Since no gate is a door, gates cannot intersect with doors or any set contained within doors, such as entrances or windows. Thus, Conclusion I is false, while Conclusion II, stating that no gate is an entrance, is logically sound and follows.

Explanation

With A in the middle position 4, F on the immediate left at position 3, E between A and D at position 5, and D at position 6, F is at position 3 and E is at position 5. Between position 3 and position 5, there is exactly one position, which is occupied by A.

Explanation

With A at the 4th position, F at 3rd, E at 5th, D at 6th, and G at 2nd (two positions away from E), C occupies the 1st position to leave one person between F and C, and B occupies the remaining 7th position. The persons sitting at the extreme ends of the row are C at the left end and B at the right end.

Explanation

The linear arrangement from left to right is C at position 1, G at position 2, F at position 3, A at position 4, E at position 5, D at position 6, and B at position 7. Facing north, the immediate right of D at position 6 is the person at position 7.

Explanation

With A facing north at position 4, the positions to the right of A are position 5 (first right), position 6 (second right), and position 7 (third right). B occupies position 7 in the final row arrangement.

Explanation

The seven positions facing north from left to right are C at position 1, G at position 2, F at position 3, A at position 4, E at position 5, D at position 6, and B at position 7. Position 7 is the rightmost position in the row.

Explanation

Arranging the digits of 59164823 in descending order gives 98654321. Comparing positions 1 through 8: Position 1: 5 and 9 Position 2: 9 and 8 Position 3: 1 and 6 Position 4: 6 and 5 Position 5: 4 and 4 Position 6: 8 and 3 Position 7: 2 and 2 Position 8: 3 and 1 The digits at position 5 and position 7 maintain their original locations.

Explanation

The first letters C (3), I (9), O (15) follow an addition of 6 positions, making the next first letter 15 + 6 = 21, which is U. Within each term, the second letter is +2 positions from the first, giving 21 + 2 = 23 (W), and the third letter is -4 positions from the second, giving 23 - 4 = 19 (S).

Explanation

Since V is 18th from the right end and E is 8th to the right of V, E is closer to the right end by 8 positions, placing E at 18 - 8 = 10th from the right end. Using the formula Position from Left = Total + 1 - Position from Right, E's position from the left end is 40 + 1 - 10 = 31.

Explanation

Sorting the digits within each three-digit number in descending order yields: 853 becomes 853 581 becomes 851 747 becomes 774 474 becomes 744 398 becomes 983 Comparing these formed numbers, 744 is the smallest value, originating from 474.

Explanation

Sorting the five numbers 853, 581, 747, 474, 398 in ascending order gives 398, 474, 581, 747, 853. The middle (third) number in this sequence is 581. Adding its individual digits gives 5 + 8 + 1 = 14.

Explanation

The given set of numbers contains 398 as the lowest number and 853 as the highest number. The third digit of the lowest number 398 is 8, and the second digit of the highest number 853 is 5. Multiplying these two digits yields 8 × 5 = 40.

Explanation

When the second and third digits of a number are interchanged, the second digit becomes the new units digit. A number is even if its units digit is even. Among the original numbers, only 581 and 747 have an even second digit, namely 8 and 4. Thus, interchanging their last two digits forms the even numbers 518 and 774.

Explanation

A number is divisible by 3 if the sum of its digits is a multiple of 3. Increasing the first digit by 1 increases the digit sum of each number by 1. The modified digit sums for 853, 581, 747, 474, and 398 become 17, 15, 19, 17, and 21, respectively. The sums 15 and 21 are divisible by 3, which corresponds to the modified numbers 681 and 498.

Explanation

The coding scheme reverses the given string and shifts the position of each character in the alphabet. Reversing OCTOBER gives R E B O T C O. Applying a forward shift of +1 to the first three characters gives S, F, and C. Applying a backward shift of -1 to the middle character gives N. Applying a forward shift of +1 to the last three characters gives U, D, and P. Combining these results produces SFCNUDP.

Explanation

B is the sister of A, which means A and B are siblings, with A being male. C is married to B. The brother of a person's spouse is their brother-in-law, so A is the brother-in-law of C.

Explanation

A is the father of G, and B is the sister of A. The daughter of one's sibling is one's niece, making G the niece of B.

Explanation

A is the father of G, who in turn is the mother of H. A mother's father is her child's maternal grandfather, making A the maternal grandfather of H.

Explanation

Setting point P at coordinates (0, 0), moving 10 km North leads to (0, 10). Turning right and traveling 15 km East leads to (15, 10). Turning left and traveling 6 km North leads to (15, 16). Finally, turning left and traveling 15 km West brings the vehicle to point Q at (0, 16). The distance between (0, 0) and (0, 16) is 16 km.

Explanation

Before taking its final turn, the vehicle was moving North. A left turn from North directs the vehicle toward the West. Thus, it was traveling West immediately prior to reaching point Q.

Explanation

Position from front = Total students - Position from back + 1. Since X is 20th from the back in a row of 34 students, the position of X from the front is 34 - 20 + 1 = 15th. W is fifth after X from the front, so the position of W from the front is 15 + 5 = 20th.
