Question

In a school are 80 teachers. It is expected that the number of teaching staff next year will increase by 5%. How many staff members should there be next year?
​

Answer 1

Answer:

84 teachers

Step-by-step explanation:

Simple trick,

If it is an increase add that percent to 100

Else if it is a decrease subtract that percent from 100. Then you multiply it with the no. of staff.

• 5% increase so, (105/100)× 80= 84 teachers
