Question 88

If the selling price is tripled and cost price doubled the profit would become 65%. What is the present profit (in %)?

Solution

Let say , selling price is s and cost price is c.

So,profit= ((s-c)/c)×100.

New profit=Let say , selling price is s and cost price is c.

So,profit= ((s-c)/c)×100.

New profit=((3s-2c)/2c)×100=65.

or, 3s/2c=1.65

or,s/c=1.1 .

present profit=(1.1-1)×100=10% .

D is correct choice.
