Question

A man sold for Rs 99 each. he sold one at a loss of 10% and the other at a gain of 10%.find his loss or gain percent.

Answer 1

Hello friend, here is your answer.

Selling price = ₹99
Loss = 10%
Cost Price = Selling price × 100/ 100 - Loss %
= 99×100/100-10
= 9900/90
= ₹110
Selling price = ₹99
Gain = 10%
Cost Price = Selling price × 100/ 100 + Profit %
= 99×100/ 100 + 10
= 9900/110
= ₹90
Total cost price = ₹(110+90) = ₹200
Total selling price = ₹(99×2) = ₹198
Loss = Cost Price - Selling Price
= ₹(200-198)
= ₹2
Loss % = Loss/Cost Price × 100
= 2/200 × 100
= 1%

Hope it helps you.
