Answer 2

Find the cost of 1 banana:

12 banana = Rs 10

1 banana = 10/12 = Rs 5/6

Find the selling Price of 1 banana:

10 banana = Rs 12

1 banana = 12/10 = Rs 6/5

Find the profit / loss :

Since Selling Price is greater than Cost Price

⇒ It is a profit

Profit = 6/5 - 5/6 = Rs 11/30

Find the profit percentage:

Profit percentage = (profit ÷ cost price) x 100

Profit percentage = ( 11/30 ÷ 5/6 ) x 100 = 44%

Answer: The banana were sold with a profit of 44%
