Question

A man sold two watches for rs 3750 each; on one he gained 5% and on the other he lost 5%. What was his total gain or loss as a percentage?

Answer 1

cost of one watch=3750rs

cost of both watches=3750+3750rs

=7500rs

He sold one of the watch at a gain of 5%

=3750+5%of3750

=3937.5rs

he sold the another watch at a loss of 5%

=3750-5%of3750

=3562.5rs

total sp =3937.5+3562.5

=7500

hence,sp=cp

therefore, no gain and no loss
