Question

When the price of rice is increased by 25 percentage , a family reduces its consumption such that the expenditure is only 10 percentage more than before . If 40 kg of rice is consumed by family before , then find the new consumption of family .
A. `35.2`
B. `35.2`
C. `36.2`
D. `37.2`

Answer 1

Correct Answer - B
(b) Suppose initial price per kg of rice is 100 then their expenditure is 4000.
Now their expenditure is only increased by only 10% i.e. 4400.
Increased price of rice=125.
So new consumption `=(4400)/(125)=35.2`
Alternate solution :
`{:(,"Price","Consumption","Expenditure"),("Old",4,40,160),("New",5,?,160+16=176):}`
`:.` New consumption `=(176)/(5)=35.2`
