In a row of boys, Mohan is 20th from the left end and 12th from the right end. Pratap is 15th from the right end of the same row. How many boys are there between Mohan and Pratap?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 2
Mohan’s two positions give the size of the row; then both boys can be placed from the left end.
Boys in the row \(=20+12-1=31\)
Pratap from the left \(=31-15+1=17\)th
Mohan is 20th from the left, so the boys between them are the 18th and 19th
Boys between \(=20-17-1=2\)
