Question

the SP is doubled then profit triples find profit percent

Answer 1

Explanation:

Let the C.P be Rs.100 and S.P be Rs.x, Then  

The profit is (x-100)

Now the S.P is doubled, then the new S.P is 2x

New profit is (2x-100)

Now as per the given condition;  

=> 3(x-100) = 2x-100

By solving, we get  

x = 200

Then the Profit percent = (200-100)/100 = 100

Hence the profit percentage is 100%
