Question

A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. What is his profit percent?

Answer 1

cost price = 26*20 + 30*36 = Rs 1600
=
selling price = 56*30( since the total mixture weights 26+30= 56 kg)
= Rs 1500
profit = S.P - C.P
= 1680-1600
=80
profit % = profit/ C.P. *100
=80/1600. *100
= 5%

Answer 2

Solution :-

Cost price = 26 × 20 + 36 × 30 = ₹ 1600

Selling price = 56 × 30 = ₹ 1680

Profit = S.P - C.P

➡ Profit = ₹ ( 1680 - 1600 )

➡ Profit = ₹ 80

Therefore,

Profit % = ( Profit / C.P ) × 100 %

➡ Profit % = ( 80 / 1500 ) × 100 %

➡ Profit % = 16/3 %

➡ Profit % = 5.33 %

Therefore the profit percentage is 5.33 %
