Question

the price of tomato goes up by 20% . by how much percent must a house wife reduce her consumption so that the expenditures dose not incresase​

Answer 1

Step-by-step explanation:

As price increase and consumption are inversely proportional,

if one increases by 1/x then other should reduce by 1/(x+1)

hence 20% is 1/5, consumption should reduce by 1/6 = 16.66%
