In a row of boys P is 13th from the left. Q is 19th from the right and 21st from the left. How many boys are there towards right of P?
Answer & explanation
Correct answer: option 2
First of all, we have to find the total number of boys in the row,
T = L + R - 1
= 21 + 19 – 1
⇒ 39
As the total number boys are 39 in the row and P is 13th from the left, therefore there will be 26 boys towards right of P.
