Question

the price of sugar is increased by 25% .by what % should the consumption of sugar is reduced so that the expenditure on its remains the same.​

Answer 1

Answer:

20%

Step-by-step explanation:

let both be 100%

So,(100/100)*(100/100)=1

So, if the price increased by 25%,total money will be 125%.If the expenditure must be same, we must have the same ans. i.e. 1

So,on equating

(125/100)*(x/100)=1,

We get x as 80%.

i.e. consumption must be reduced by 100%-80%=20%
