Question

If I rencently decreased my average number of products sold per week by 15% I now sell an average of 21.25 products per week. Previously how many products was I selling per week?

Answer 1

Alright, lets get started.

Suppose previously I was selling product per week = x

As per question, I have decreased my average number of product by 15 %

Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x

So, the new average product = x - 0.15 x = 0.85 x

As per given question, the new average product = 21.25

0.85 x = 21.25

Dividing by 0.85 in both sides

0.85 x / 0.85 = 21.25 / 0.85

x = 25

Hence it means, 25 products were selling previuosly. : Answer

Hope it will work :)
