Answer»

⇒ Average = sum of elements / number of elements

Given,

Let the initial production be 100.

Increase in the production of cloths in the FIRST month is 20% =

= 100 + 100 × (20/100)

= 120

Increase in the production of cloths in the second month is 25% =

= 120 + 120 × (25/100)

= 120 + 30

= 150

Increase in the production of cloths in the third month is 15% =

= 150 + 150 × (15/100)

= 150 + 22.5

= 172.5

There is increment in production =

= 172.5 - 100

= 72.5

The average increase RATE =

= 72.5/3

= 24.16
