1. The cost of picture frame M is Tk.10.00 less than 3 times the cost of picture frame N. If the cost of frame M is Tk.50.00, what is the cost of frame N?
- A. Tk.13.33
- B. Tk.13.33
- C. Tk.13.33
- D. Tk.13.33
Answer: Option C
Explanation:
Cost price of N = x
Cost price of M = 3x - 10
3x - 10 = 50
= > 3x = 60
= > x = 60/3
∴x = 20
