By selling an article for 3600$, a man takes profit of 20%. What would his gain % be if he sold the article for 4,000$

28%

Step-by-step explanation:

3600$ * 20%

=3600 * (20/100)

=3600 * 0.2

= 720

Actual Price = 3600 - 720

= 2880

Profit is at 4000$ = 4000 - 2880

= 1120$

%profit = (1120/4000) * 100

profit = 28%

Answer:33.3%

Step-by-step explanation:

20 = (3600-cp) / cp * 100

20cp=100 (3600-cp)

20cp=360000-100cp

20cp+100cp=360000

120cp=360000

Cp=360000/120 cp=3000

%gain when selling price is 4000 = (4000-3000) / 3000 * 100

1000/3000*100 = (1000*100) / 3000=100000/3000=33.3%
