1. A person bought an article and sold it at a loss of 10%. If he had bought it for 20% less and sold it for Tk.55 more he would have had a profit of 40%. The CP of the article is--
- A. 250
- B. 250
- C. 250
- D. 250
Answer: Option A
Explanation:
Let C.P. = Rs. P
Then S.P. = Rs. (90/100) x P = Rs. (9 x P)/10
New C.P. = Rs. (80/100) x P = Rs. (4 x P)/5
Now, Gain = 40%
∴ New S.P. Rs. (140/100 x 4P/5) = Rs. 28P/25
∵ 28P/25 - 9P/10 = Rs. 250
Then S.P. = Rs. (90/100) x P = Rs. (9 x P)/10
New C.P. = Rs. (80/100) x P = Rs. (4 x P)/5
Now, Gain = 40%
∴ New S.P. Rs. (140/100 x 4P/5) = Rs. 28P/25
∵ 28P/25 - 9P/10 = Rs. 250
