Question

A grocer wishes to mix spice at Rs. 8 /kg with another sort at Rs. 5 /kg to make 60 kg to be sold at Rs. 6 /kg . What quantity of each must he take?

Answer 1

Step-by-step explanation:

Find the cost price of 5 kg of mixture:

Cost of 2 kg of butter @Rs 500 per kg = 2 x 500 = Rs 1000

Cost of 3 kg of butter @ Rs420 per kg = 3 x 420 = Rs 1260

Total cost = 1000 + 1260 = Rs 2260

Find the cost price of the 250g of the mixture:

5 kg = Rs 2260

5000 g = 2260

1 g= 2260 ÷ 5000 = Rs 0.452

250g = 0.452 x 250 = Rs 113

Find the profit percentage:

Profit = 150 - 113 = Rs 37

Profit percentage = 37/113 x 100 = 32.74%

The mixture is sold at a profit of 32.74%
