Answer 1

Given:

Cost of 10 kilograms of apples of type 1 = Rs. 100 per kg

Cost of 10 kilograms of apples of type 2 = Rs. 180 per kg

To find:

The price at which the shopkeeper must sell the mixed apples to make a profit of 90%.

Solution:

Cost of 10 kilograms of apples of type 1 = Rs. 100*10 = Rs. 1000

Cost of 10 kilograms of apples of type 2 = Rs. 80*10= Rs. 800

Total cost price of apples = Rs. 1000+800 = Rs. 1800

Profit percent to be made= 25%

Profit= (25/100)*1800

= Rs. 450

Selling price of all the 20 kg apple= Profit+ cost price

= Rs. 450+ Rs. 1800 = Rs. 2250

Selling price of 1 kg of apple = Rs. 2250/20 = Rs. Rs. 112.5

The shopkeeper must sell the apples at a cost of Rs. 112.5 per kg.
