Correct option is A
Given:
In a queue, Sameer is 32nd from the left and Aman is 8th to the right of Sameer.
If Aman is 24th from the right in this queue.
According to given information;

Total number person = 31 person before Sameer + Sameer + 7 Person between Sameer and Aman + Aman + 23 person after Aman
Total number person = 31 + 1 + 7 + 1 + 23
Total number person = 63
So, 63 is the total number of persons in the queue.
Thus, the correct answer is (a).
