Question

If A`s salary is 20% less then B`s salary , by how much percent is B`s salary more than A`s

Answer 1

Let's say, B's salary = 100

Therefore, A's salary = 80(100-20)

Percentage of B's salary less than A = (100 - 80)/80%

                                                             = 25%.

                                          Hope this helps!

Answer 2

salary of B=100
then salary of A=80
percent of B salary more than A=(100-80/80)*100
20/80*100
25%
