What is the difference between the number of employees who prefer travelling by Metro from companies D and E together and the number of employees who prefer travelling by bus from companies A, D & E together?
1162
Calculation:
The number of employees who prefer to travel by metro together from companies D and E = \(\dfrac{70 \times 182}{14} + \dfrac{72.5 \times 220}{12.5}\) = 2186
The number of employees who prefer to travel by bus together from companies A, D, and E \(\dfrac{24 \times 184}{8} + \dfrac{16 \times 182}{14} + \dfrac{15 \times 220}{12.5}\) = 1024
Difference = 2186-1024 = 1162
∴ The difference between the number of employees who prefer to travel by metro together from companies D and E and the number of employees who prefer to travel by bus together from companies A, D, and E is 1162.
