Question

The salary of a worker is first increased by 10%, and thereafter it was reduced by 10%. What is the change in the salary after these adjustments?

• A. \(-2\%\)
• B. \(-3\%\)
• C. \(-4\%\)
• D. \(-1\%\)

Answer 1

The Correct Option is A

Let the original salary of a person be 100 Rs.
His salary first increased by 10%.
\(⇒ 100\times (\frac{110}{100})\)
110 Rs.
After some time his salary is reduced by 10%.
\(⇒ 110\times (\frac{90}{100})\)
\(⇒ \)99 Rs.
Now, his final salary is 99 Rs. which is 1% less than his original salary.
Hence, the correct answer is -1%
The correct answer is (D):\(-1\%\)
