Question

A man sell two watches at rs240 each and by doing 25% on one and loss 25% on the other. does he gain a loss on the whole ?by how much?

Answer 1

net effect formula can be used here that is-

x+y+xy/100

here, X= 25% , Y= -25% ( loss )

Using the formula-

25-25+(25× -25)/100= 0-625/100

-6.25% ( sign - denotes loss)

he faced loss of 6.25%
