Question

The price of sugar goes up by 25%. By how much per cent must a house wife
reduce her consumption of sugar so that the expenditure does not increase.​

Answer 1

Step-by-step explanation:

Let the price of sugar before increase = ₹100

then, price after increase = ₹100 + ( 25% of ₹100)

= ₹100 + ( 25/100 × ₹100)

= ₹100 + ₹25

= ₹125

So, house wife should decrease the consumption by

(25/125 × 100)%

= 20%
