1.      I) What is the percentage increase of arun salary?

Ii) What is the percentage increase of huberta salary?

iii) Percentage increase in huberta salary is how much percent greater than the percentage increase in arun salary?

iv) What is the percentage point change in the salary of huberta and arun?

Solution:

i)                    12,000-10,000/10,000 x 100  = 20%

Or 2/10 --à 1/5 = 20%

ii)                  2/8 = 1/4 = 25%

iii)                Percentage increase of huberta salary = 25

Percentage increase of arun salary = 20

So the required percentage = 25-20/20 x 100 = 25%

It means percentage increase of huberta salary is 25% greater than the percentage increase of arun salary.

iv)                Percentage point change = (Percentage increase in huberta salary – Percentage increase in arun salary)

= 25-20 = 5 percentage point
