Answer 1

Answer:

cost of 1 banana is rs 30

cost of 1 banana = 30/12

cost of 8 banana = 8×(30/12)

= 20

Answer 2

If a banana cost Rs. 30 per dozen, the cost of 8 bananas is given as follows,

From given we have,

A banana cost Rs. 30 per dozen

⇒ 12 bananas = Rs. 30

For 12 bananas the cost is Rs. 30

To calculate the cost of 8 bananas, we need to find the cost of 1 banana.

Therefore, we have,

1 banana = Rs. 30 / 12

∴ 1 banana = Rs. 2.5

For 8 bananas, we have,

8 × 1 banana = 8 × Rs. 2.5

8 bananas = Rs. 20

The cost of 8 bananas is Rs. 20
