By selling two articles for Rs. 800, a person gains the cost price of three articles. The profit percent is:
A. 125
B. 140
C. 120
D. 150
Answer: Option D
Solution (By Examveda Team)
Selling price of 2 → 8001 → 400
Let cost price of one article = x
Gain at 2 articles = 3x
1 article = $$\frac{{3{\text{x}}}}{2}$$
Selling price = x + $$\frac{{3{\text{x}}}}{2} = \frac{{5{\text{x}}}}{2}$$

Profit % = $$\frac{3}{2}$$ × 100 = 150%
