In a class of 40 students, Prateek is placed eighth from the top, whereas Sonu is placed thirteenth from the bottom. Ashish is placed exactly between the two. What is Sonu's position from Ashish?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 10
Sonu is 13th from the bottom of 40, so from the top he is 40 − 13 + 1 = 28th, while Prateek is 8th from the top.
Ashish stands exactly midway between the 8th and the 28th places, that is at (8 + 28)/2 = 18th from the top. Sonu is therefore 28 − 18 = 10 places from Ashish.
