Step-by-step explanation:

Let the price of Rice be= ₹60/ Kg.

Due to increase of 20% price rise the cost of Rice/Kg will be = ₹ 60 x 1.20 = ₹72.

So for ₹ 72 the weight of rice that can be bought= 60/72= 5/6 - kg.

Therefore if he reduces the consumption by 1/6 x 100= 16.67%, the expenditure will remain unchanged.
