If the selling price is tripled, the profit becomes 5 times. What is the profit percent?
Let the Cost Price be Rs.100 and Selling Price be Rs.x
Then, Profit = Rs.(x - 100)
New Selling Price = Rs.3x
Then, New profit = Rs,(3x-100)
Given, 3x-100 = 5(x-100) => 2x = 400 => x = 200
Hence, Selling Price = Rs.200
Profit percentage = $$\dfrac{200-100}{100}\times100 = 100$$%
