Solution
Let the original salary be x. It is given that the new salary is Rs 1,54,000.
Original salary + Increment = New salary
However, it is given that the increment is 10% of the original salary.
Therefore
`x + 10/100 xx x = 154000`
`(110x)/100 = 154000`
x= `(154000 xx 100/110)`
x = 140000
Thus, the original salary was Rs 1,40,000.
