Question

a man starts job with a certain monthly salary and earns a fixed increment every year. if his salary was 1500 after 4 year of service and 1800 after 10 year service. what was his starting salary and what is annual increment

Answer 1

after 4 years salary was 1500

after 10 years salary was 1800

subtract year and salary will give increment in 6 years

(10 - 4) = 1800 - 1500

so increment in 6 years = 300

increment per year = 50 per year
