Question

A man starts his job with a certain increment every year if his salary will be 1500 after 4 years and 1800 after 10 years of his service what is his starting salary and what is the annual increment?

Answer 1

salary of the man after 4 years=1500 and
salary of the man after 10 years =1800
difference between no of years =10-4
=6years
difference in the salary=1800-1500
=300
so annual increment
= 300/6
=50
starting salary of the man
=1800-(50*10)
=1800-500
=1300
