The groundnuts are bought at Rs. 20 per kg . The processing cost is rs 5 per kg. At what price (Rs.per kg) should the oil be sold to earn 20% profit on total costs. (Total cost= Cost of groundnuts and Processing costs).

Answer 1

Answer:

Rs 100 per kg

Step-by-step explanation:

To have 20% profit groundnut should sold at Rs 30 per kg

And in 1 kg 0.8 kg cattle feed came out that would cost 12.5*0.8=Rs10

Now we need Rs 20 from 0.2 kg of oil so oil cost = 20/0.2=Rs 100 per kg

Answer 2

Answer:

Step-by-step explanation:

The total cost of ground nut is rs.25

We need 20% profit so we need to sell it at rs 30.

We gain rs 10 by selling as cattle feed.( 12.5*.8=10)

Now we want rs. 20 more.

So we need to sell it at rs 100.
