Solutions

S1. Ans.(b)
Sol. Clearly, there are five odd numbers between ‘T’ and ‘C’ in the given series.

S2. Ans.(a)
Sol. Clearly, ‘W’ is 17th to the left of ‘L’.

S3. Ans.(b)
Sol. 5T, 7Y, 8K, 5M, 4B, 6D
Clearly, there are six consonants which are immediately preceded by a number which is greater than 3.

S4. Ans.(d)
Sol. 8th number from the left end = 7
8th number from the right end= 9
Clearly, their sum is 16.

S5. Ans.(c)
Sol. Clearly, the element which is preceded by a ‘0’ and immediately followed a vowel is seventh to the right of Y.

S6. Ans.(d)
Sol. Given Series = 759 594 396 444 372 423
second-highest number- 594
second-lowest number- 396
Resultant = 5 ÷ 3 = 1.6

S7. Ans.(a)
Sol. Given Series = 759 594 396 444 372 423
After subtraction = 759 593 395 333 371 313
Therefore, option a is the correct answer.

S8. Ans.(b)
Sol. Given Series = 759 594 396 444 372 423
After rearrangement = 372 396 423 444 594 759
Required difference = 594 – 423 = 171
Therefore, option B is the correct answer.

S9. Ans.(c)
Sol. Given Series = 759 594 396 444 372 423
After adding 1 = 859 694 496 544 472 523
After interchange = 958 496 694 445 274 325
Therefore, option C is the answer.

S10. Ans.(d)
Sol. Given Series = 759 594 396 444 372 423
After interchange = 579 954 936 444 732 243
Therefore, option D is the correct answer.

S11. Ans.(d)
Sol. K Z 3 + T % & I H N ! 8 $ J Q 1 L M * @ Y R 2 4 # D F =

S12. Ans.(e)
Sol. In all other groups, the 3rd and 4th elements occupy the same positions from the right in the given arrangement as the first and 2nd elements respectively from the left end.

S13. Ans.(b)
Sol. In each pair, the 1st, 2nd and 3rd elements of the 1st term move 4, 7 and 1 steps forward respectively to give the corresponding elements of the 2nd term.

S14. Ans.(e)
Sol. K Z 3 + T % & I H N ! 8 $ J Q 1 L M * @ Y R 2 4 # D F =

S15. Ans.(e)
Sol. K Z 3 + T % & I H N ! 8 $ J Q 10 L M * @ Y R 2 4 # D F =
