1. Salam earns Tk. 8.50 per hour on days other than Friday and twice the rate on Friday. Last week he worked a total of 50 hours including 8 hours on Friday. What is his earning for the week?
- A. Tk. 340
- B. Tk. 340
- C. Tk. 340
- D. Tk. 340
Answer: Option D
Explanation:
During the week, Salam worked a total of 50 - 8 = 42 hours at a rate of Tk. 8.50 per hour.
On Friday, he worked 8 hours at a rate of Tk. 8.50 × 2 = Tk. 17.00 per hour.
Total earnings for the week = 42 × 8.50 + 8 × 17 = TK. 493.
