Question 64

The price of sugar is increased by 21%. A person wants to increase his expenditure by 12% only. By what percent, correct to one decimalplace, should he reduce his consumption?

Solution

Let a man buy 100 kg of sugar in Rs 100

21% price increased then,

100 kg price will be Rs 121

Man increased his expenditure by 12% = 112

Rs 121=100 kg sugar

Rs 112= $$\frac{11200}{121}=92.60 kg\ $$

So he have to reduce his consumption by 100 - 92.60= 7.40 %
