Solutions

S1. Ans.(b)
Sol. Clearly, ‘I’ is 15th to the right of 15th element from the left end.

S2. Ans.(d)
Sol. Clearly, there are seventeen elements between G and the element which is to the immediate right of X.

S3. Ans.(a)
Sol. Clearly, there is no number which is immediately preceded by a consonant and immediately followed by a number.

S4. Ans.(c)
Sol. Clearly, ‘F’ is ninth to the left of the one which is second to the left of ‘B’.

S5. Ans.(b)

S6. Ans.(a)
Sol. 7th element from the left end= U and its place value is 21
8th element from the right end= L and its place value is 12
Clearly, their sum is 33.

S7. Ans.(b)
Sol. Clearly, there are ten consonants (FDSZXCVHJK) between ‘β’ and ‘∑’ in the given series.

S8. Ans.(a)
Sol. Clearly, ‘S’ is eighteenth to the left of 6th element from the right end.

S9. Ans.(b)
Sol. Clearly, there are nine letters which are immediately preceded by a symbol and immediately followed a letter.

S10. Ans.(b)
Sol. Clearly, ‘J’ is 17th to the right of the one which is 4th consonant from the left end.

S11 Ans.(d)
Sol. After interchange – 268 348 586 955 497
So, second lowest number = 348. So, 439 is the answer.

S12. Ans.(d)
Sol. After rearrangement – 962 943 875 965 984
So, 857 is lowest number.

S13. Ans.(b)
Sol. After rearrangement – 269 349 578 569 489
So, 857 is the answer.

S14. Ans.(c)
Sol. After interchange – 926 934 758 695 849
So, 9 will be the second digit of the lowest number.

S15. Ans.(b)
