Step-by-step explanation:
Let the salary before the increment be Rs.100. Then,
Increase in salary =Rs.10
∴ Increased salary =Rs.(100+10)=Rs.110
If increased salary is Rs. 110, original salary =Rs.100
If increased salary is Rs. 154000, original salary =Rs.(110100×154000)=Rs.140000
Hence, the salary of the man before increment was Rs.140000.
