In a row of boys, A is 10th from the left and B is 9th from the right. If A is 5th to the left of B, how many boys are there in the row?
Show answer & explanation
Correct answer: A
Explanation
A is 5th to the left of B.
If A = 10th (from the left), then
B = 10 + 5 = 15th (from the left).
B is 9th from the right.
Total boys = B's left + B's right − 1
= 15 + 9 − 1
= 23
