Determine the starting monthly salary and the fixed annual increment of an employee in a company whose salary after 4 years of service reached 15,000 and after 10 years of service reached 18,000 dollars per month?
If x & y are starting salary and fixed annual increment of the employee respectively. Then from question:
x + 4 y = $ 15,000 - Eq. I
and x + 10 y = $ 18,000 - Eq. II
Subtracting Eq. I from Eq. II, we get:
6 y = $ 3,000
⇒ y = $ 500
Substitute value of y = $ 500 in Eq. I:
x + 4 ($ 500) = $ 15,000
x = $ 15,000 - $ 2, 000 = $ 13, 000
So, the starting salary is $ 13, 000 and fixed annual increment is $ 500.
The starting salary of the employee is $ 13, 000 and his fixed annual increment is $ 500.
