Question

Vijay's salary was reduced by $50$%. Again the reduced salary was increased by $50$%. Then what will be the % loss in salary?

Answer 1

Let the salary =100 Rs.
Reduce=50%
Now salary=50 Rs.
then 50% of 50=$\frac{50}{100}\times 50=25Rs$
Now salary=$50+25=75Rs.$
$loss=100-75=25$
loss %=$\frac{25}{100}\times 100=25$%
