Answer 2

Solution!!

The concept of unitary method has to be used here. We have to find the cost of 1 quintal of soyabean and then the cost of 8 quintals.

→ Cost of 12 quintals = Rs 36,000

Now, we have to find the cost of 1 quintal. So, we will divide.

→ Cost of 1 quintal = Rs 36,000 ÷ 12

→ Cost of 1 quintal = Rs 3,000

We know the cost of 1 quintal of soyabean so we can easily find out the value of 8 quintals by multiplication.

→ Cost of 8 quintals = Rs 3,000 × 8

→ Cost of 8 quintals = Rs 24,000

The cost of 8 quintals of soyabean is Rs 24,000.
