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%
