Question

A vegetable vendor buys 10 kg of tomatoes per day at ₹ 10 per kg, for the first three days of a weak. 1 kg of tomatoes got smashed on every day for those 3 days. For the remaining 4 days of the week, he buys 15 kg of tomatoes daily at ₹ 8 per kg. If for the entire week he sells tomatoes at ₹ 20 per kg, then find his profit or loss for the week.

Answer 1

Total tomatoes bought for 3 days = 3 × 10 = 30 kg

Cost of 1 kg = ₹ 10

Cost of 30 kg tomatoes = 30 × 10 = ₹ 300

Total tomatoes bought for other 4 days = 4 × 15 = 60 kg

Cost of 1 kg = ₹ 8

Cost of 60 kg tomatoes = 60 × 8 = ₹ 480

Total cost of 90 kg tomatoes = 300 + 480 = ₹ 780

C.P = ₹ 780

Tomatoes smashed = 3 kg

Total kg of Tomatoes for sale = 90 – 3 = 87 kg

S.P of 1 kg tomatoes = ₹ 20

S.P of 87 kg tomatoes = 87 × 20 = ₹ 1740

Here S.P > C.P

Profit = S.P – C.P = 1740 – 780 = ₹ 960

Profit = ₹ 960
