Question

on a school picnic,a group of students agree to pay equally for the use of full boat and pay rupees 10 each.if there had been 30 more students in the group, each would have paid rupees 2 less.how many students were there in the group.

Answer 1

let number of students be a
money paid is 10a

new number of students is a+30
money to be paid is 8(a+30)

10a=8(30+a)
10a=240+8a
2a=240
a=120
therefore number of students is 120
