Solutions

S1. Ans. (b)
Sol. Given Series – 437 341 669 492 136
After operation – 347 431 669 942 316
Second digit of the largest number – 4 (942)
Third digit of the smallest number – 6 (316)
So, required multiplication – 4 x 6 – 24

S2. Ans. (b)
Sol. Given Series – 437 341 669 492 136
Sum – 14 8 21 15 10
After adding all the digits of every number, we find that 341’s sum is be smallest.

S3. Ans. (b)
Sol. Given Series – 437 341 669 492 136
After removing first number – 37 41 69 92 36
So, there are two numbers (69, 36) which are divisible by 3.

S4. Ans. (d)
Sol. Given Series – 437 341 669 492 136
After operation – 347 134 669 249 136
So, third largest number – 492

S5. Ans. (b)
Sol. Given Series – 437 341 669 492 136
Second digit of the highest number – 6
Second digit of the lowest number – 3
So, required division – 2

S6. Ans. (d)
Sol. Given Series – 7 H β 5 % T I M 6 $ E 8 G 3 S N @ A # C D 4 8 U & D
After dropping – H β % T M $ G S N @ # C D D
Therefore, option (d) is correct.

S7. Ans. (c)
Sol. Given Series – 7 H β 5 % T I M 6 $ E 8 G 3 S N @ A # C D 4 8 U & D
Required reversal – S 3 G 8 E $ 6 M I T % 5 β H 7 N @ A # C D 4 8 U & D
Therefore, option (c) is the correct answer.

S8. Ans. (d)
Sol. Given Series – 7 H β 5 % T I M 6 $ E 8 G 3 S N @ A # C D 4 8 U & D
After changing – 7 I β 5 % U J N 6 $ F 8 H 3 T O @ B # D E 4 8 V & E
Therefore, option (d) is the correct answer.

S9. Ans. (c)
Sol. Given Series – 7 H β 5 % T I M 6 $ E 8 G 3 S N @ A # C D 4 8 U & D
Therefore, option (c) is the correct answer.

S10. Ans. (d)
Sol. Given Series – 7 H β 5 % T I M 6 $ E 8 G 3 S N @ A # C D 4 8 U & D
Therefore, option (d) is the correct answer.
