The Correct Option is A

Solution and Explanation

Let the original salary of a person be 100 Rs.
His salary first increased by 10%.
100×(110100)⇒ 100\times (\frac{110}{100})
110 Rs.
After some time his salary is reduced by 10%.
110×(90100)⇒ 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%-1\%
