S1. Ans. (e)

S2. Ans. (d)

S3. Ans. (b)

S4. Ans. (e)

S5. Ans. (a)

S8. Ans.(b)
Sol. Clearly, Ashish is 15th from the right and
Neha is 12th from the right end and 10th from the left end of the row
So, number of students in the row = (12 -1 + 10) = 21
Now, Ashish is 15th from the right
Number of boys to the left of Ashish= (21+1-15)
Hence, A is 7th from the left end of the row.
