Question

A man sells two pens at Rs.40 each. He sells one at a gain of 10% and the other at a loss of 10%.

Find his gain or loss %.

Answer 1

Answer:

when he sells at a gain of of 10% he gets 40+4= 44

When he sells at a loss of 10% he gets (90/100)×40=36

44+36= 80 = 40+40 So neither gains nor lods
