## Question

**If selling price is doubled, the profit triples. Find the profit percent ?**

A. 400%

B. 300%

C. 200%

D. 100%

#### Answer: D. 100%

**Solution:**

Let the cost price be Rs.100 and selling price 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%**
