In a row of 40 children, P is thirteenth from the left end and Q is tenth from the right end. How many children are there between Q and M if M is fourth to the right of P?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 13
Write every position from the same end, here the left, and then count the places in between.
P is 13th from the left
M is 4th to the right of P: \(13+4=17\)th from the left
Q is 10th from the right in a row of 40: \(40-10+1=31\)st from the left
Children between M and Q: \(31-17-1=13\)
