Question

A grocer bought sugar worth of rupees- 4500 . He sold one - third of it at a gain of 10% . At what gain % must the remaining sugar be sold to have a gain of 12% on the whole?

Answer 1

Given: CP = 4500

Profit on 1/3 of theof the sugar = 10%

Amount = (4500/3)*(110/100)

= 150*11 = 1650

Profit = 1650 - 1500 = 150

Total amount required = 4500*112/100 = 5040

Total profit should be 5040 - 4500 = 540

Required profit on the remaining part of the sugar = 540 - 150 = 390

Let the profit on the remaining part of sugar be x

amount by selling 2/3 of the sugar = (4500)*(2/3)*(x/100) = 390

= 30x = 390

= x = 390/30 = 13

Therefore, profit on the remaining part of the sugar = 13%
