Find the next number in the series: 64, 34, 19, 11.5, 7.75, ?
Correct answer: B
Each term is obtained by halving the previous term and adding 2: 64/2+2=34, 34/2+2=19, 19/2+2=11.5, 11.5/2+2=7.75, 7.75/2+2=5.875.

Statement: A school opened its library at 7 a.m. Which conclusion is most reasonably supported, without adding assumptions?
Correct answer: B
Opening earlier directly benefits students who are already at school early, so the modest, directly supported conclusion is that those with early schedules may now have access — it does not claim every student's behavior changes.
A chisel is used for carving in the same way that a broom is used for which activity?
Correct answer: D
A chisel is the tool used to carve, and a broom is the tool used to sweep — each tool is paired with its characteristic action.
A candidate is 6th from the bottom in a group of 19 candidates. What is the candidate's position from the top?
Correct answer: C
Position from the top = total - position from bottom + 1, so 19 - 6 + 1 = 14th.
A delivery person walks 10 m east, then 10 m north, then 10 m west. What is the final displacement from the starting point?
Correct answer: A
The 10 m east and 10 m west legs cancel out, leaving only the 10 m north leg as the net displacement.
A compass indicates direction in the same way that a calendar indicates which information?

A sieve is used for separation in the same way that a filter is used for which process?
Correct answer: A
A sieve separates particles by size, and a filter removes impurities from a substance — both instruments clean or sort material by letting some of it pass through.
A parcel is 11th in a queue of 30 parcels waiting to be dispatched. What is its position counted from the end of the queue?
Correct answer: C
Position from the end = total - position from the start + 1, so 30 - 11 + 1 = 20th.
Find the next number in the series: 2, 5, 9, 14, 20, ?
Correct answer: C
The gap between consecutive terms increases by 1 each time (+3, +4, +5, +6, +7), so 20 + 7 = 27.
In the list Rose, Lotus, Lily, Wheat, which item does not belong with the others?
Correct answer: C
Rose, Lotus, and Lily are flowers, while Wheat is a cereal crop, not a flower.
Statement: A firm introduced a monthly budget review. Which conclusion is most reasonably supported, without adding assumptions?
Correct answer: A
Reviewing the budget monthly gives managers more frequent checkpoints, so the modest, directly supported conclusion is that unfavorable variances may be caught sooner — it does not guarantee profit or eliminate losses.
Find the next number in the series: 4, 7, 5, 8, 6, 9, ?
Correct answer: D
The series alternates +3 then -2: 4→7(+3)→5(-2)→8(+3)→6(-2)→9(+3)→7(-2), so the next term is 7.
A runner finishes 8th from the front in a field of 25 runners. What is the runner's position from the back?
Correct answer: B
Position from the back = total - position from front + 1, so 25 - 8 + 1 = 18th.
Given the statements: Some farmers are musicians. All musicians are disciplined. Which conclusion follows?
Correct answer: C
Since some farmers are musicians, and every musician is disciplined, those particular musical farmers must be disciplined — so at least some farmers are disciplined.
What is the area of a rectangle? (1) Its length is 12 cm. (2) Its width is 5 cm. Which statement(s) are sufficient to answer the question?
Correct answer: A
Area requires both length and width; neither dimension alone is enough, but together they give area = 12 x 5 = 60 sq cm.
A trekker walks 12 steps west, then 5 steps south. How far is the endpoint from the starting point?
Correct answer: B
The west and south legs form a right angle, so the direct distance is the square root of (12 squared + 5 squared) = the square root of 169 = 13 steps.
Punit is the father of Qadir, and Qadir is the father of Rhea. How is Punit related to Rhea?
Correct answer: B
Punit is the father of Rhea's father Qadir, which makes Punit Rhea's grandfather.
What is the average of a, b and c? (1) a + b + c = 42. (2) c = 10. Which statement(s) are sufficient to answer the question?
Correct answer: C
The average only requires the sum divided by the count: Statement 1 alone gives 42 / 3 = 14. Statement 2 alone gives only one of the three values, which is not enough.
A cyclist rides 4 blocks north, then 3 blocks east, then 4 blocks south. What is the final displacement from the starting point?
Correct answer: A
The 4 blocks north and 4 blocks south cancel out, leaving only the 3 blocks east as the net displacement.
Six friends A, B, C, D, E and F sit in a row facing the same direction. A is second from the left. F is at the right end. C sits immediately to the left of D. B is not adjacent to A. Who sits at the left end?
Correct answer: D
With A=2 and F=6, testing the two ways to place the consecutive pair C-D among the remaining seats shows only C=3, D=4 avoids placing B next to A; that leaves B=5 and forces E into seat 1, the left end.
In a line of students, Kavya is 9th from the front and 14th from the back. How many students are in the line?
Correct answer: D
Total = position from front + position from back - 1 (Kavya is counted once), so 9 + 14 - 1 = 22.
Given the statements: All poets are readers. No reader is silent. Which conclusion follows?
Correct answer: A
Since every poet is a reader, and no reader is silent, it follows that no poet can be silent either.
Find the next number in the series: 100, 91, 75, 52, 22, ?
Correct answer: C
The amount subtracted each time increases by 7 (-9, -16, -23, -30, -37), so 22 - 37 = -15.
