Question

questions first)a shopkeeper purchased of banana at rupees 18 per dozen and sold 10 bananas at the rateof rupees 18.find the gain or loss percent.

Answer 1

Find the cost price of 1 banana:

12 bananas = Rs 18

1 banana = 18 ÷ 12 = Rs 1.50

Find the selling price of 1 banana:

10 bananas = Rs 18

1 banana = 18 ÷ 10 = Rs 1.8

Find the profit / loss:

Since Selling Price > Cost Price ⇒ It is a profit

Profit = Rs 1.80 - Rs 1.50 = Rs 0.30

Find the profit percentage:

Profit Percentage = Profit / Cost Price  x 100

Profit Percentage = (0.30 ÷ 1.50 ) x 100 = 20%

Answer: The bananas were sold at a profit of 20%
