उत्तर

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%
