Question 1: If in a certain language, 'ROSE' is coded as 'TQUG', how is 'BLUE' coded?

DNWG (Correct answer)
CNVF
DMWH
CLVF

Correct answer: DNWG

The coding pattern involves shifting each letter forward by two positions in the alphabet. R (+2) -> T, O (+2) -> Q, S (+2) -> U, E (+2) -> G. Applying the same logic to 'BLUE': B (+2) -> D, L (+2) -> N, U (+2) -> W, E (+2) -> G.

Question 2: Find the next number in the series: 2, 5, 10, 17, 26, ?

35
37 (Correct answer)
38
39

Correct answer: 37

The pattern is based on the difference between consecutive terms. The differences are 3 (5-2), 5 (10-5), 7 (17-10), and 9 (26-17). This is a series of consecutive odd numbers. The next difference should be 11. Therefore, the next number is 26 + 11 = 37.

Question 3: In a certain code, 'BREAK' is written as '51342' and 'KITE' is written as '2796'. How is 'RIBB' written in that code?

1755 (Correct answer)
1752
1355
1722

Correct answer: 1755

This is a direct substitution code where each letter is assigned a specific digit. From 'BREAK', we get R=1 and B=5. From 'KITE', we get I=7. Therefore, to code 'RIBB', we substitute the corresponding digits: R -> 1, I -> 7, B -> 5, B -> 5. The code is 1755.

Question 4: Find the missing term in the series: A, D, I, P, ?

W
X
Y (Correct answer)
Z

Correct answer: Y

The series is based on the alphabetical position of the letters, which are perfect squares. A is the 1st letter (1²), D is the 4th letter (2²), I is the 9th letter (3²), and P is the 16th letter (4²). The next term will be the 25th letter (5²), which is Y.

Question 5: If 'GO' = 32 and 'SHE' = 49, then 'SOME' will be equal to?

54
56 (Correct answer)
58
60

Correct answer: 56

The code is the sum of the reverse alphabetical positions of the letters (A=26, Z=1). For 'GO': G's reverse is T(20) and O's reverse is L(12), so 20+12=32. For 'SHE': S's reverse is H(8), H's reverse is S(19), E's reverse is V(22), so 8+19+22=49. For 'SOME': S(8) + O(12) + M(14) + E(22) = 56.

Question 6: What is the next term in the series: 3F, 6G, 11I, 18L, ?

27P (Correct answer)
27O
25P
25O

Correct answer: 27P

The series consists of two separate patterns, one for numbers and one for letters. The number pattern is 3, 6, 11, 18; the difference increases by 2 each time (+3, +5, +7). The next difference is +9, so 18+9=27. The letter pattern is F, G, I, L; the gap between letters increases by 1 each time (+1, +2, +3). The next gap is +4, so L (+4) -> P. The next term is 27P.

Question 7: If 'COMPUTER' is coded as 'DQPVUTER', what is the code for 'LAPTOP'?

MBQTOP (Correct answer)
MBQUPQ
LAPTQP
MBSUPQ

Correct answer: MBQTOP

The pattern is an alternating +1, +1, +1, +1 shift for the first half of the word, and the second half remains the same. COMP -> DQP V. UTER -> UTER. Applying this to 'LAPTOP': The first half is 'LAP', so L(+1)->M, A(+1)->B, P(+1)->Q. The second half 'TOP' remains unchanged. The code is 'MBQTOP'.
