1. The difference between the cost price and sale price of an article is Tk. 240. If the profit is 20%, the selling price is:
- A. Tk. 1240
- B. Tk. 1240
- C. Tk. 1240
- D. Tk. 1240
Answer: Option A
Explanation:
Hints: ধরি cost price x তাহলে 20% profit এ sell price হবে
x + x এর 20%
= x + 0.2x
= 1.2x
1.2x - 1x = 240
.2x = 240
x = 1200
Selling price = 1200 + 240 = 1440
