Question

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

Answer 1

28%

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 2

Answer:33.3%

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%
