Q2 of 7 Page 171

On selling 36 oranges, a vendor loses the selling price of 4 oranges. Find his loss percent.

Let cost price and selling price of one orange be Rs. c and Rs. s respectively.


⇒ Cost Price of 36 oranges = 36 × c = 36c and


Selling Price of 36 oranges = 36 × s = 36s


Given Loss = Selling Price of 4 oranges


⇒ Loss = 4s


But, we know Loss = Cost Price – Selling Price


⇒ 4s = 36c – 36s


⇒ 40s = 36c



We have,





But, s = 0.9c




Thus, loss percentage is 10 (that is 10% loss).
