Question

A school has 600 pupils. 1/5 are in the upper school, 1⁄4 in the middle school and

the remainder in the lower school. How many pupils are in the lower school?

Answer 1

Explanation:

the number of pupils are in the lower school

= (1- 1/5 - ¼) × 600

= (20/20 - 4/20 - 5/20)×600

= (11/20) ×600

= 330 pupils
