Question

A trader gain 25% by selling an article for a certain price. If he sells it at double the price, then find the profit percent.

1. 100%
2. 120%
3. 140%
4. 150%
5. 200%

Answer 1

Correct Answer - Option 4 : 150%

Formula used:

SP = CP + Profit

Calculations:

Let CP = 100%

⇒ SP = CP + P

⇒ SP₁ = 100% + 25% = 125%

If SP is doubled, SP₂ = 2 × 125% = 250%

Here CP = 100%

⇒ P = SP – CP

⇒ P = 250% - 100%

⇒ P =150%

⇒ P% = (150%/100%) × 100

∴ Profit percentage is 150%
