Question

In the new budget the price of kerosene oil rose by 25%
By how much % must a person reduce his consumption
so that there is no effect on expenditure?​

Answer 1

Answer:

reduction in consumption  = 20 %

Step-by-step explanation:

Increased (r) % = 25 % .

Reduction in consumption = $(\frac{r}{r + 100}* 100 )$ %

                                             = $(\frac{25}{25 + 100} * 100 )$ =  20 %

So the reduction in consumption  = 20 %
