Solutions
S1. Ans.(d)
Sol. All other groups except (d) consist of prime numbers only, while (d) consists of one composite number i.e. 91. Hence, the answer is (d).

S2. Ans.(d)
Sol. Except (d), the number inside the bracket is the sum of the cubes of the numbers outside it.
125 + 216 = 341

S3. Ans.(c)
Sol.
Same pattern follow by DREAMER -> CQDBLDQ

S4. Ans.(a)
Sol. The relations may be analysed as follows:
Daughter of brother-in-law – Niece;
Mother’s neice – Cousin.
So, the girl is the cousin of Rehana’s friend.

S5. Ans.(c)
Sol. Clearly, the lady is the grandmother of man’s sister’s son i.e., the mother of the mother of man’s sister’s son i.e., the mother of man’s sister.

S6. Ans.(d)
Sol.
As shown in figure, the man initially faces in the direction OA. On moving 135° anti-clockwise, he faces in the direction OB. On further moving 180° clockwise, he faces in the direction OC, which is South-west.

S7. Ans.(b)
Sol. ‘Chillies’ are green in colour and as given, ‘chillies’ are ‘bananas’. So, ‘bananas’ are green in colour.

S8. Ans.(c)
Sol. In all other numbers, the middle digit is equal to the Subtraction of 1st and 3rd digit.
So, 982 = 9-2 = 7, that means number should by 972.

S9. Ans.(c)
Sol. All others indicate disorder of health.

S10. Ans.(d)
Sol. M and N are 13th and 14th letters of the English alphabet respectively. So, 13+1 = 14,  14+1 = 15
So, M × N corresponds to 14 × 15.
Similarly, F and R are 6th and 18th letters of the English alphabet respectively. 6+1 = 7, 18+1 = 19
So, F × R corresponds to 7 × 19.

S11. Ans.(a)
Sol. All are agricultural practices.

S12. Ans.(c)
Sol. The series is abcd/bcad/cabd/abcd/bcad/cabd. Clearly, each group consists of letters of the previous group in the order – second, third, first and fourth.

S13. Ans.(b)
S14. Ans.(c)
Sol. Clearly, the given sequence is a combination of two series:
I. 1, 3, 7, ?, 31
and II. 3, 13, 23, 33
The pattern followed in I is +21, +22, 23, 24… and the pattern followed in II is +10.
So, missing number = 7 + 23 = 15.

S15. Ans.(c)
Sol. HILARIOUS
