Question

A man sells two radios for rs 4000 each. For one he gets a gain of 20% and for the other a loss of 20%. Find his total loss or gain in the whole transaction.

Answer 1

There is 1600 profit as 4800 - 3200 = 1600

Answer 2

sp is 4000
so cp of 20% gain radio is =4000(1-20/100)
=4000*(4/5)
=800*4
=3200
so cp of 20% loss radio is =4000(1+20/100)
=4000*(6/5)
=800*6
=4800
then total cp is =4800+3200=8000
so no loss no profit.................(ans)
