Answer 1

Given : dhiraj purchased 150kg of rice .he sold 1/3 of it at 10%loss.

To Find : at what percent of profit must he sell the remaining rice so that he can make 10% profit on the whole

Solution:

Rice = 150 kg

Let say cost per kg rice = C  Rs  

Total Cost Price = 150C  Rs

10 % Profit = (10/100)150C = 15C  Rs

Total Selling Price = 150C + 15C = 165C  Rs

1/3 = (1/3)150 = 50 kg  

10 % Loss  => SP  = C - (10/100)C  = 0.9C

Selling Price of 50 kg Rice = 50 * 0.9C = 45C

Selling price of remaining 150 - 50 = 100 kg Rice

= 165C - 45C  = 120C  Rs

Selling price of 1 kg rice = 120C/100  = 1.2C  Rs

Profit Per kg = 1.2C - C = 0.2C Rs

Profit % = (0.2C/C) * 100 = 20 %

He must sell remaining at 20 % profit
