Answer :

New salary of the man= ₹ 1,54,000

Given, the increase in salary = 10%

New salary of the man = Original salary \(\times\) (1 + \(\frac { Increase }{ 100 }\))

\(\Rightarrow\) 154000 = Original salary \(\times\) (1 + \(\frac{10}{100}\))

\(\Rightarrow\) 154000 = Original salary \(\times\) (\(\frac{110}{100}\))

\(\Rightarrow\) Original salary=\(\frac{154000\times 100}{110}\)

\(\Rightarrow\) Original salary= ₹ 1,40,000.

Thus, the original salary = ₹ 1,40,000
