Question

a man sells good at a 30% profit. if the cost of the goods double and the profit percenet becine half of its present valud

Answer 1

Total cost including profit = 100%
Profit = 30%
Cost = 100%-30% = 70%

Value becomes half:
Profit = (30/2)% = 15%
Cost = (70/2)% = 35%

I have doubt on this. But still I gave this question a shot from my side. Do comment whether my answer was right or wrong.
