Question

If the selling price is doubled and the profit triples, find the profit percent.

विकल्प

• `66 2/3`%

• 100%

• `105 1/3`%

• 120%

Answer 1

100%
Explanation : 
Let CP be ₹ x and SP be ₹ y.
Then, 3(y - x) = (2y - x)
⇒  y = 2x
   Profit = ₹(y - x) = ₹(2x - x) = ₹ x

∴  Profit% = `(x/x×100)%` = 100%
