Step-by-step explanation:
Solution:
Let the original salary be Rs.100.
Therefore New salary i.e., 10% increase
= 100 + 10 = Rs.110
\because∵ New salary is Rs.110, when original salary = Rs.100
\therefore∴ New salary is Rs.1, when original salary = \frac{100}{110}
110
100
\therefore∴ New salary is Rs.1,54,000, when original salary = \frac{100}{110}\times154000=Rs.\ 1,40,000
110
100
×154000=Rs. 1,40,000
Hence original salary is Rs. 1,40,000.
