Nitin's salary was reduced by 10% and then the reduced salary was increased by 10%. His new salary in comparison with his original salary is
1). the same
2). 1% more
3). 1% less
4). 5% less
.Let Nitin’s initial salary be 100
After 10% reduction,
New salary = 90% of 100 = 90
Again after 10% increase
New salary =$\frac{90\times110}{100}$ =99
Percentage decrease =1 %
