Question
A man got a 10% increase in his salary. If his new salary is Rs 1,54,000, find his original salary.
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.
