Question

Farhan buys 200 kg of onions at ₹12 per kg. 10% of the onions are spoiled. Find the selling price per kg if he wants to earn 40% profit on the cost price

Answer 1

He buys 200 kg of onions at 12

10% are spoiled = 10/100×200 = 20 kg are spoil

Cost price of 1 kg onions = 200÷12 = 16.66

total money he spend in buying i.e cost price of onions = 16.66 × 200 = 3333.33 rupees

As we know that 20 kg is spoiled so he is only left with 200 - 20 = 180 kg of onions

And he wants to make 40% profit per kg so

selling price per kg in order to make 40% profit will be = 40 ÷ 100 × 16.66 = 6.664 rupees

so adding the profit into CP = 16.66 + 6.664

= 23.324 rupees

So he needs to sell the onions at rupees 23.324 per kg in order to earn a profit of 40%
