The price of a commodity is increased by 36% and the quantity purchased is decreased by 30%. What is the percentage increase/decrease in the amount spent on the commodity?
Let the price of 100kg commodity is Rs 100
After increased in price
100 kg = Rs 136
Now quantity of commodity decreased = 70 kg
70 kg commodity price =Â $$\frac{70\times\ 136}{100}=Rs\ 95.20$$
Decreased in amount = 100 - 95.20 = 4.8%.
