Answer 1

The cost price of 1 kg of grain should be 52.5 rupees.

Step-by-step explanation:

Consider the provided information.

A trader buys grain at rs.30 per kg,

Let trader buys 100 kg grain.

Then the cost price of 100 kg grain is 3000.

20%of the grain gets wasted.

That means reaming grain is 80% of 100 or 80kg.

He want 40% profit.

$3000+\frac{40}{100} \times 3000=3000+1200=4200$

Hence, the selling price should be 4200 where the quantity of grain is 80 kg.

The cost of 1 kg grain should be: $\frac{4200}{80}= 52.5$

Hence, the cost price of 1 kg of grain should be 52.5 rupees.
