If the prices of apples goes down by 10%, find the percentage of increase that a family should effect in its consumption so as not to increase expenditure on this account.

Percentage increase in consumption of apples by the family = 11.11%

Step-by-step explanation:

Price of apples goes down by 10% which means apples  would now cost $90.

So for $100 the family can buy  = apples

Increase in consumption =New consumption-Previous consumption=

Taking LCD.

apples is the increase in consumption

Percentage increase in consumption=
