Question

If the price of rice is reduced by 20%, then by how many% increase the consumption so that there is no effect on the expenditure?

Answer 1

Answer:

25%

Step-by-step explanation:

Let the original price of rice be rupees 100

price of rice reduced by 20%

Decreased price in tea= 100-(20/100)=100-20= Rs 80

decreased price= 100-80 = rs 20

Rice of cost Rs.20 is to increased out of the decreased cost of Rs.80

Percentage decrease = 20/80 * 100 = 25

therefore 25% of rice consumption is to be increased.
