A man's salary is 30000Rs per month. His annual increment is 15000 Rs. What will be his salary after 20 years of service?

Question

Maths problem

Answer 1

the underlying formula that you want to use here is

Final Monthly Salary = Initial Monthly Salary + Total Incremental Increase over 20 Years

for the values given in this question that means taking

30,000 + 20(15,000)

=30,000 + 300,000

=330,000

meaning that his salary after 20 years of service will be 330,000 Rs per month

Answer 2

To find his current annual salary:

12 x 30000 = 360,000 RS per year

Now we find the total increment after 20 years:

15,000 RS x 20 = 300,000 RS

We add his current salary to the increment after 20 years :

360,000 RS + 300,000 RS = 660,000

After 20 years, his salary will be 660,000 Rs.
