A class boys stands in a single line. One boy is nineteenth in order from both the ends. How many boys are there in the class?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 37
When the same boy is counted from both ends he is counted twice, so the total is (position from one end) + (position from the other end) − 1.
Here that is 19 + 19 − 1 = 37 boys — the boy stands exactly in the middle, with 18 on each side.
