Question

the price of a commodity has increased by 60% by what percent must the consumer reduce the consumption of the commodity so as not to increase the expenditure​.plz Tell me only if you know the answer​

Answer 1

Answer:

let initial price be 100rs and quantity be 1000grms

now increased price=160 and quantity will remain same that is 1000

160 rs = 1000

1rs=1000/160

100rs=(1000/160)×100=625grms

earlier we were able to buy 1000grms in 100rs but now we are able to buy only 625 grms in 100rs

so decrease in quantity=1000-625=375grms

% decrease =(375/1000)×100=37.5%
