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.
