Solution
If 20 lemons are bought for ₹ 10 and sold at 5 for three rupees, then profit in the transaction is 20 %.
Explanation:
Cost price of 20 lemons = ₹ 10
∴ Cost price of 1 lemon = `10/20` = ₹ `1/2`
Selling price of 5 lemons = ₹ 3
∴ Selling price of 1 lemon = ₹ `3/5`
Now, S.P. > C.P.
Therefore, profit in the transaction = `3/5 - 1/2` = ₹ `1/10`
Profit % = `(1/10)/(1/2) xx 100 = 1/10 xx 2/1 xx 100` = 20%
