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 X x = 154000

100x/100 = 15400

x = ( 154000 X 100/100 )

x = 140000

Thus , the original salary war Rs 1,40,000.
