In a class boys stand in a single line. One of the boys is seventeenth in order from both the ends. How many boys are in the class?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 33
A boy who is 17th from one end has 16 boys on that side of him; being 17th from the other end too, he has 16 boys on the other side as well.
Total \(=16+1+16=33\)
Tip: Total \(=\) position from the left \(+\) position from the right \(-\,1\), here \(17+17-1=33\). Adding the two positions without taking away 1 counts the boy twice and gives 34, Option (1).
