Answer 1

Find the cost of 1 lemon:

Total lemon = 3 + 4 = 7

Total cost = 2 + 3 = Rs 5

7 lemons = Rs 5

1 lemon = Rs 5/7

Find the selling price if 1 lemon:

5 lemons = Rs 4

1 lemon = Rs 4/5

Find the profit/loss percentage:

5/7 < 4/5 ⇒ It is a profit

Profit = Selling Price - Cost Price

Profit = 4/5 - 5/7 = Rs 3/35

Profit percentage = (profit ÷ cost price) x 100

Profit Percentage =( 3/35 ÷ 5/7 ) x 100 = 12%
