Answer 1

Given,

First type of rice = 40 kg

Price of first type of rice = Rs. 6.75/kg

Second type of rice = 60 kg

Price of second type of rice = Rs. 8/kg

To find,

The selling price to vai get 20% profit.

Solution,

First of all, we have to calculate the total cost price.

Cost price of first type of rice

= 40×6.75

= Rs. 270

Cost price of second type of rice

= 60×8

= Rs. 480

Total cost price = (480+270) = Rs. 750

Total rice = 40+60 = 100 kg

Profit amount = 750 × 20/100 = Rs. 150

Selling price = 750+150 = Rs. 900

Price per kilogram = 900/100 = Rs. 9

Hence, the selling price will be Rs. 9/Kg
