    C) Rs. 8000                       

    D) None of these

    Correct Answer: D

    Solution :

    Let initial salary\[=Rs.\,22x\] Final salary\[=Rs.\,25x\] Let initial number of employees \[=3y\] Final number of employees\[=2y\] \[\therefore \] Present bill = Final salary \[\times \] Final number of employees \[\Rightarrow \]   \[5000=2x\times 2y\] \[\Rightarrow \]   \[\frac{5000}{50}=xy\] \[\Rightarrow \]   \[xy=100\] Original bill = Initial salary x Initial number of employees             \[=22x\times 3y\]             \[=66xy=\text{ }66\times 100=Rs.\,6600\]
