Question

A wheat vendor uses 1200 g instead of 1kg while buying and uses 900 g instead of 1 kg while selling . He also adds 5 kg of brown stone per 100 kg. If he gives a discount of 10 % , find his profit or loss accrued?

Answer 1

Let us assume that he buys 100kg of wheat at $10/kg to start with. Also let us assume that he sells at the same price as he buys.

Amount bought for = 100 * 10 = $1000

Actual quantity bought = 1.2 * 100 = 120kg

Brown stone added = 5/100 * 120 = 6kg

Total quantity for sale = 126kg

Sale price (after 10% discount) = $9

Amount sold for = 126 *9 / 0.9 = $1260 (as he uses only 900gm to weight 1 kg)

Total profit = 1260 - 1000 = $260

Profit % = 26% <- Ans.
