Question

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

• A. $150000$
• B. $140000$
• C. $123000$
• D. $123445$

Answer 1

The correct option is B $140000$

Let us assume the initial salary $=100$

So, Salary after hike $=100+10$% of $100$

$=100+10=110$

$\because$ When increased salary is $110$, initial salary $=100$

$\because$ When increased salary is $1$, the initial salary $=\frac{100}{110}$

$\therefore$ When increased salary is $154000$,

the initial salary $=\frac{100}{110}\times 154000=140000$
