# What is the Change in His Salary? If

The salary of a worker is first increased by 10% and then it is decreased by 10%, what is the change in his salary:

- 1% decrease
- 1% increase
- 2% decrease
- 2% increase

**Answer: (1) 1 % decrease**

**Explanation:-**

Let the salary of a worker is Rs.100

The salary increased by 10 %,

Then, the salary = 100 + 100 x 10/100

= 100 + 10

= Rs.110

And the salary decreased by 10 % ,

Then, the salary of the worker = 110 – 110 x 10/100

= 110 – 11

= Rs.99

Loss = 100 – 99

= Rs.1

Loss % = 1 x 100/100

= 1 %

Hence, the answer is (1) 1 % decrease.
