Question

The number of students in a school increased by 8% anually.If there are 71280 students in the school then how many students were there leat year?​

Answer 1

Answer:

There were 66,000 students last year

Step-by-step explanation:

Let the number of students last year = x

Given: number of students grow by 8 per cent each year.

Accordingly,

x + 8% of x = 71280

[No. of students last year + 8% of number of students last year = No. of students this year]

x + 0.08x = 71280

1.08x = 71280

x = (71280/1.08)

x = 66000

The number of students last year = 66,000
