In a class, the 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 3
The correct answer is Option 3: 37
If one boy is 19th from the beginning and 19th from the end, then the total number of boys is:
$\text{Total} = 19 + 19 – 1$
(The boy is counted twice, so subtract 1.)
$= 38 - 1 = 37$
