A shop keeper purchased 15 kg of sugar and 20 kg of wheat at Rs. 50 and Rs. 75 per kg respectively. On selling them, he gained 10% on sugar…

As per the given data

Cost price of the 15 kg of sugar = 15 × 50 = Rs. 750

Cost price of the 20 kg of wheat = 20 × 75 = Rs. 1500

Given that profit on sugar is 10% and on wheat is 20%

⇒ Profit on sugar = profit%/ 100 × cost price of sugar = 10/100 × 750 = Rs. 75

⇒ Selling price on sugar = profit + cost price of sugar = 75 + 750 = Rs. 825

⇒ Profit on wheat = profit%/100 × cost price of wheat = 20/100 × 1500 = Rs. 300

⇒ Selling price on wheat = profit + cost price of wheat = 300 + 1500 = Rs. 1800

∴ Total sale value = selling price of sugar + selling price of wheat = 825 + 1800 = Rs. 2625

Shop keeper purchased 15kg at 50 rupees = 750

20kg of wheat at 75 rupees = 1500

Profit on sugar = 750+75 = 825

Profit on wheat = 1500+300 = 1800

Total value = 1800+825 = 2625
