Answer 1

p per cent 6×100/45
40/3%

Answer 2

Find the cost price of 1 banana:

10 bananas = Rs 45

1 banana = 45 ÷ 10 = Rs 4.50

Find the selling price of 1 banana:

12 bananas = Rs 51

1 banana = 51 ÷ 12 = Rs 4.25

Find the profit / loss:

Selling Price  <  Cost Price ⇒ It is a loss

Loss = Cost Price - Selling Price

Loss = 4.5 - 4.25 = Rs 0.25

Find the loss percentage:

Loss Percentage = Loss / Cost Price x 200

Loss Percentage = 0.25 / 4.50 x 100 = 5.56%

Answer: It is sold at a loss of 5.56%
