Percentage
10. The price of tea has gone up by 20 %. By how much percent should its consumption be reduced so as not to increase the expenditure?
Let price of tea be Rs `100` per kg
`:.` new price of tea = Rs `( 100 + 20 )` = Rs `120` per kg
Now not to increase the expenditure, its consumption must be reduced by Rs `20`
New Price Rs
Reduced Consumption Rs
120
20
100
?
Reduced Consumption = `(100 × 20) / 120 = 16.6667` Rs
`:.` Consumption must be reduced by Rs `16.6667` , if original price of tea be Rs `100`
`:.` Consumption must be reduced by `16.6667` % for not to increase the expenditure.
