Question

There are some benches in a classroom . If 5 students sit on each bench , three benches

are left vacant and if 3 students seat on each bench 5 are left standing . What is the total

number of students in the class ?​

Answer 1

Step-by-step explanation:

Let no. Of benches =x

No. Of students =y

5 students sit on bench and 3 left vacant

y=5x-5*3

y=5x-15 ----------(1)

If 3 students sit on each bench and 5are left standing

y=3x-5 ------------(2)

From 1and 2

5x-15=3x-5

2x=10

x=5
