Question

A men buys two pens at rupess 20 each he sells one at a gain of 5% and other at a loss of 5% find his gain or a loss per cent

Answer 1

Cost price of the two pens is ₹ 20 each.


So total cost price = ₹ 20 + ₹ 20 = ₹ 40

with gain of 5% on first pen

gain = 5% of 20 = 0.05 of 20 = ₹ 1

so Selling price of first pen = ₹ 20 + 1 = ₹ 21

with loss of 5% on second pen

loss = 5% of 20 = 0.05 of 20 = ₹ 1

so Selling price of second pen = ₹ 20 - 1 = ₹ 19

So, total Selling price = ₹ 21 + ₹ 19 = ₹ 40

Hence , SP - CP = 0

So no loss no gain.
