Question

if selling price is doubled the profit become triple.Find the profit percent?

Answer 1

It's so simple 300 percent.

Answer 2

Good question I must say
Okay let's see
Let
CP be x
SP be y
then profit well be y-x

Again we have give that
SP is doubled= 2y
profit will be= 2y-x
so
2y-x=3(y-x)
2y-x=3y-3x
y=2x
But profit is=y-x
=2x-x
=x.
Profit percentage will be=x*100/x
=100%.
