Question

sandesh sold 15 kg apples for ₹2100 and made a profit of 12%. at what price per kg should he sell to get 20% profit?​

Answer 1

First count selling price using 15% profit

Selling price = [(100+15%)/100] x Cost.Price

Selling price = 1.15 x 2100

Selling price = Rs 2415

Selling price of 15kg apple will be Rs. 2415

So, selling price of 1kg will be Rs.161
Because ,
2415/15 = 161 Rs per kg

At 12.5% profit price of one kg was Rs.140

At 15% profit price of one kg is Rs. 161

Therefore Sandesh should sell increasing at Rs. 21 per kg to make a profit of 15%

Answer 2

Price of 15kg = RS 2100

Price of 1 kg = 2100÷15=140

Profit included =12%

Profit per 1Kg = 12%of RS 140= RS 16.8

To make profit 20%

20% of 140

= RS 28

RS 28 must be taken for 1 kg to make profit of 20%
