In a certain code, FRAME is written as GSBNF. Using the same rule, how should GREEN be written?
Correct answer: B
Every letter of FRAME is shifted one place forward in the alphabet (F to G, R to S, A to B, M to N, E to F). Applying the same +1 shift to GREEN gives HSFFO.
Seven students L, M, N, O, P, Q and R sit in a row. L is third from the left. Q sits at the right end. M sits immediately to the left of N. O sits between P and R. Which person's seat can be determined with certainty, even though the order of P and R relative to each other is not fixed?
Correct answer: B
With L=3 and Q=7, the only two seats left forming a consecutive pair for M-N are 1 and 2, forcing P, O and R into seats 4, 5 and 6; since O must be the middle of that block regardless of which side P and R sit on, O's seat (5) is fixed.
Find the next number in the series: 8, 11, 17, 26, 38, ?
Correct answer: B
The gap between consecutive terms increases by 3 each time (+3, +6, +9, +12, +15), so 38 + 15 = 53.
Four candidates — Mira, Nitin, Ojas and Ritu — scored differently in a test. Mira scored higher than Nitin but lower than Ojas. Ritu scored lower than Nitin. Who scored the highest?
Correct answer: A
The clues establish the order Ojas > Mira > Nitin > Ritu, so Ojas scored the highest.
In a certain code, RIVER is written as SJWDQ. What is BRAVE written as, using the same rule?
Correct answer: A
The first three letters shift forward by 1 and the last two shift back by 1 (R+1=S, I+1=J, V+1=W, E-1=D, R-1=Q). Applying the same pattern to BRAVE gives CSBUD.
Varun is the mother of Waseem, and Waseem is the brother of Xena. How is Varun related to Xena?
Correct answer: A
Since Waseem and Xena are siblings, Waseem's mother Varun is also Xena's mother.
Five colleagues F, G, H, I and J sit in a row. H sits exactly in the middle. F sits at the left end. J sits immediately to the right of I. Who sits second from the left, immediately to the right of F?
Correct answer: A
With F=1 and H=3, the only remaining consecutive pair for I-J among seats 2, 4 and 5 is (4,5), which leaves seat 2 — immediately right of F — for G.
In a garden, four beds — roses, herbs, tomatoes and lilies — are arranged around a central point. The roses bed is east of the herbs bed. The tomatoes bed is west of the herbs bed. The lilies bed is north of the tomatoes bed. Which bed lies exactly between the roses bed and the tomatoes bed on the east-west line?
Correct answer: A
Since the roses bed is east of the herbs bed and the tomatoes bed is west of the herbs bed, the herbs bed sits directly between the two on the east-west line.
In a certain code, CROWN is written as NWORC. Using the same rule, how should PLANT be written?
Correct answer: B
The code simply reverses the letters of the word (CROWN reversed is NWORC). Reversing PLANT in the same way gives TNALP.
A book is 7th from the thinnest end on a shelf of 28 books. What is its position from the thickest end?
Correct answer: D
Position from the other end = total - given position + 1, so 28 - 7 + 1 = 22nd.
Is k a positive number? (1) k squared equals 9. (2) k is greater than -1. Which statement(s) are sufficient to answer the question?
Correct answer: D
Statement 1 alone allows k = 3 or k = -3, so the sign is unknown. Statement 2 alone allows many values, including 0 and negative fractions. Together, only k = 3 satisfies both, confirming k is positive.
Statement: A farm tested soil moisture before irrigation. Which conclusion is most reasonably supported, without adding assumptions?
Correct answer: A
Testing soil moisture provides data the farm can act on, so the modest, directly supported conclusion is that irrigation can be adjusted to actual conditions — it does not guarantee yield or eliminate all wastage.
Starting from a point, a person walks 5 units north and then 12 units east. How far is the endpoint from the origin?
Correct answer: B
The north and east legs form a right angle, so the direct distance is the square root of (5 squared + 12 squared) = the square root of 169 = 13 units.
Who is taller, A or B? (1) A is taller than C. (2) C is taller than B. Which statement(s) are sufficient to answer the question?
Correct answer: D
Neither statement alone compares A and B directly. Combined, A > C and C > B chain together to give A > B.
A boat travels 20 m east, then 21 m north. What is the straight-line distance from the starting point?
Correct answer: B
The east and north legs form a right angle, so the direct distance is the square root of (20 squared + 21 squared) = the square root of 841 = 29 m.
Given the statements: No birds are mammals. Some bats are mammals. Which conclusion follows?
Correct answer: D
Since some bats are mammals, and no bird is a mammal, those particular mammalian bats cannot be birds — so at least some bats are not birds.
Five people P, Q, R, S and T sit in a row. P sits in the middle seat. Q sits at the left end. R sits at the right end. S sits immediately to the left of P. Who sits immediately to the right of P?
Correct answer: D
With P=3, Q=1 and R=5, S must occupy seat 2 (immediately left of P), which leaves T in seat 4 — immediately to the right of P.
Given the statements: Some books are old. No old thing is digital. Which conclusion follows?
Correct answer: C
Since some books are old, and nothing old is digital, those particular old books cannot be digital — so at least some books are not digital.
Four crates — Blue, Green, Red and Yellow — are ordered by weight. Blue is heavier than Green but lighter than Red. Yellow is lighter than Green. Which crate is the heaviest?
Correct answer: A
The clues give the order Red > Blue > Green > Yellow, so Red is the heaviest crate.
What is the value of x? (1) x + 7 = 19. (2) x is an integer. Which statement(s) are sufficient to answer the question?
Correct answer: D
Statement 1 alone solves directly for x = 12. Statement 2 alone only says x is an integer, which does not pin down a single value.
Six people U, V, W, X, Y and Z sit in a row. Z sits at the left end. U is second from the right. X sits immediately to the left of Y. W is not adjacent to U. Who sits at the right end?
Correct answer: D
With Z=1 and U=5, the pair X-Y must occupy seats 3 and 4 (the only option that keeps W away from seat 5's neighbours), leaving W in seat 2 and V in seat 6, the right end.
Find the next number in the series: 12, 21, 13, 31, 14, 41, ?
Correct answer: A
The series interleaves two sequences: 12, 13, 14, ... and 21, 31, 41, ...; the next term continues the first sequence, giving 15.
A player is 4th from the front and 23rd from the rear in a line-up. How many players are in the line-up?
Correct answer: A
Total = position from front + position from rear - 1, so 4 + 23 - 1 = 26.
A robot moves 9 cm left, then 12 cm down. What is the straight-line distance from the starting point?
Correct answer: D
The left and down legs form a right angle, so the direct distance is the square root of (9 squared + 12 squared) = the square root of 225 = 15 cm.
