If the SP is doubled, the profit triples. Find the P%

Answer»

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

3x - 300 = 2x - 100

3x - 2x = -100 + 300

x = 200

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

Hence the profit percentage is 100%
