Correct Answer: D [(3, 10, 101)]

Explanation:

Each number is the square of the previous + 1: 2² + 1 = 5, 5² + 1 = 26; 3² + 1 = 10, 10² + 1 = 101.

2.  
Letter analogyCFIL : XURO :: DGJM : ?

Correct Answer: C [WTQN]

Explanation:

Each letter is replaced by its opposite (positions add up to 27): D–W, G–T, J–Q, M–N.

3.  
Odd pairSelect the odd pair: (2, 6), (3, 12), (4, 20), (5, 28)

Correct Answer: B [(5, 28)]

Second = n(n + 1): 2 × 3, 3 × 4, 4 × 5; but 5 × 6 = 30, not 28.

4.  
Wrong termFind the wrong term in the series: 2, 4, 10, 29, 82, 244

Correct Answer: A [29]

Explanation:

Each term is 3 × previous − 2: 2, 4, 10, 28, 82, 244 – the fourth term should be 28.

5.  
Number seriesWhich number comes next? 1, 3, 8, 18, 35, 61, ?

Correct Answer: C [98]

Explanation:

Differences 2, 5, 10, 17, 26 are n² + 1; next difference 37 → 61 + 37 = 98.

6.  
Number codingIn a certain code, SKY = 165 and CAT = 72. What is the code for NET?

Correct Answer: B [117]

Explanation:

(Sum of letter positions) × (number of letters): SKY (19 + 11 + 25) × 3 = 165; NET (14 + 5 + 20) × 3 = 117.

7.  
Coding–decodingIn a code language, 'sky is blue' is written as 'mo ri tu', 'blue sea is deep' as 'tu ka ri zo', 'deep and wide' as 'ka ne pi' and 'sky and sea' as 'mo ne zo'. What is the code for 'sea'?

Correct Answer: A [zo]

Explanation:

blue/is = tu/ri, so sea/deep = ka/zo; deep = ka (3rd sentence) → sea = zo, which also fits the 4th sentence.

8.  
Coded inequality'@' means '>', '#' means '<', '%' means '=', '&' means '≥' and '©' means '≤'.
Statements: P © Q, Q @ R, R % S
Conclusions: I. Q @ S II. P @ S

Correct Answer: D [Only I follows]

Explanation:

Decoded: P ≤ Q > R = S. Q > S is definite (I).

9.  
Interchange signsWhich two signs should be interchanged to make the equation correct?
10 ÷ 2 − 13 × 14 + 19 = 70

Correct Answer: C [Interchange − and ×]

Symbolic operationIf 7 ⊕ 3 = 410, 9 ⊕ 5 = 414 and 6 ⊕ 2 = 48, then 8 ⊕ 3 = ?

Correct Answer: D [511]

Explanation:

Write (a − b) followed by (a + b): 7 − 3 = 4, 7 + 3 = 10 → 410.
