Anil is 12th from the left end of a row and Sunil is 15th from the right end. When they exchange their places, Anil becomes 20th from the left. How many persons are there in the row?

Correct answer: A

Explanation

Anil's new place is Sunil's old place, which is 20th from the left and 15th from the right, so the row has 20 + 15 − 1 = 34 persons.
