Question

Gautam bought 30 kg of rice at 25 rs per kg and 40 kg of rice at 28 rs per kg. He mixed the two varieties and sold the mixture at 36 rs per kg. Find his gain in the whole transaction.

Answer 1

Answer:650 rs

Step-by-step explanation:

Gautam bought 30kg of rice at 25rs per kg

Then total price of 30kg rice=30×25=750rs_ _ _(1)

Then he bought 40 kg of rice at 28rs per kg

Then total price of 40kg of rice=40×28=1120rs_ _ _(2)

Total price of rice=(1)+(2)=750+1120=1870rs

Therefore,purchased price=1870rs_ _ _(3)

Total amount of rice=30kg+40kg=70kg

He sold 70kg of rice at 36rs per kg

Then sold price=70×36=2520rs_ _ _(4)

Gain=(4)-(3)

=2,520-1,870

=650rs

Therefore,gain=650rs
