The ratio of the efficientics of X.Y and Z is `:3:4:5`. The total amount of wates of X.Y and Z working for 20 days. 10 days and 12 days respectively was Rs. 6400. Find the amount of their total wages, if X,Y and Z worked for 30 days, 15 days, and 8 days respectively (in Rs.)

Options

A. 5700
B. 9500
C. 7600
D. 8850

Explanation

To solve the problem step by step, we will follow the given information and calculate the required wages for X, Y, and Z.

### Step 1: Understand the efficiency ratio
The efficiencies of X, Y, and Z are given in the ratio of 3:4:5.

Let the efficiencies be:
- Efficiency of X = 3k
- Efficiency of Y = 4k
