Ex 8.2 | Question 1

Text Solution

What is known?

Percentage of increase in salary \(= 10\%\)

New Salary \(=\rm{ Rs}\, 1,54,000\)

What is unknown?

Original Salary


Whole is considered as \(100\%\). Percentage increase is \(10\%\). So, the new salary is original salary plus \(10\%\)of original salary


Let the original salary be \(x\)

Percentage increase is \(10\%\)

Therefore, Original salary \(+\) Increment in salary \(=\) New salary

\[\begin{align}x + 10\%  \times x &= 154000\\x + \frac{{10}}{{100}} \times x & = 154000\\


Original salary is \( \rm{Rs}\, 1,40,000\)
