1. A wholesaler bought 1200 radios for Tk. 18 each. The wholesaler sold 60 percent of the radios for Tk. 30 each and the rest for Tk. 15 each. What is the wholesaler's average (arithmetic mean) profit per radio?
- A. Tk. 6
- B. Tk. 6
- C. Tk. 6
- D. Tk. 6
Answer: Option A
Explanation:
Cost price = 1200×18 = 21600
Revenue = (60% of 1200)×30 + (40% of 1200)×15 = 21600 + 7200 = 28800
Profit = 28800 - 21600 = 7200
Profit per radio = 7200 / 1200 = 6 TK.
