Question

In X class, if three students sit on each bench, one student will be left. If four students sit on
each bench, one bench will be left. Find the number of students and the number of benches
in that class.​

Answer 1

Answer:

The number of students 16

The number of benches 5

if 3 students sit on each bench 3*5=15 then one student will be left.

But when 4 students sit on each bench 3*4=16

or we can say 16 bench/ 4 on each bench =4 bench needed. Means 1 bench left.
