1. An employer pays 3 workers X, Y and Z a total of Tk.610 or 36600.00 a week. X is paid 125% of the amount of Y is paid and 80% of the amount of Z is paid. How much does X make a week?
- A. Tk.150 or 8500
- B. Tk.150 or 8500
- C. Tk.150 or 8500
- D. Tk.150 or 8500
Answer: Option E
Explanation:
X = 125% of y = 125y/100 = 5y/4
Or, y = 4x/5
Again,
X = 80% of z = 80z/100 = 4z/5
Or, z = 5x/4
X:y:z = x:4x/5:5x/4 = 20:16:25
Sum of ratio = 20 + 16 + 25 = 61
So, x makes a week = 20/61 × 36600 = 20×600 = 12000 tk. (ans)
