Question

the price of a sugar goes up by 30%.by what percent should a housewife reduce her consumption so that the expenditure does not increase.

Answer 1

Let price of 100kg sugar be=100rs
Price goes up by 30% , therefore new price= 130rs

In 130rs quantity of sugar can be purchased =100kg
In 100rs quantity of sugar can be purchased =100×100/130
=1000/13kg
Difference in consumption
=100/1-1000/13
=1300-1000/13
=300/13kg

% of reduction= 300/13/100×100
= 23×1/13%.

Thank you,
