Given : salaries of A and B are 10% and 30% less than that of C respectively
To Find : By what percentage (approx) is the salary of A more than that of B.
Solution:
Let say Salary of C = 100S
salaries of A 10 % less than that of C
=> Salary of A = 100S - (10/100)100S = 90S
salaries of B 30 % less than that of C
=> Salary of B = 100S - (30/100)100S = 70S
Salary of A more than that of B. = 90S - 70S = 20S
percentage (approx) is the salary of A more than that of B. = (20S / 70S) * 100
= 200/7
= 28.57 %
