A wholesaler deals in wheat. He mixes 50 kg of wheat at Rs. 40 per kg with 30 kg of wheat of other kind of wheat at Rs. 60 per kg and sells the new mixture at Rs. 90 per kg. Find the profit percentage. Correct Answer 89.47%

Given:

Quantity of first kind of wheat = 50

Price of first kind of wheat = Rs. 40 per kg

Quantity of second kind of wheat = 30 kg

Price of second kind of wheat = Rs. 60 per kg

Selling price of mixture = Rs. 90 per kg

Calculation:

Cost price of first kind of wheat = Rs. 2000

Cost price of second kind of wheat = Rs. 1800

Cost price of 80 kg wheat = Rs. 3800

Selling price of 80 kg of wheat = 80 × 90

⇒ Rs. 7200

Profit = 7200 – 3800

⇒ Rs. 3400

Profit percentage = (3400 / 3800) × 100

⇒ 89.47%

∴ The required profit percentage = 89.47%
