Question

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

Answer 1

Answer:

Step-by-step explanation:

His starting salary = Rs.1300 and fixed Increment = Rs.50  

Step-by-step explanation:

Let his salary be x and his fixed increment be y.

After 4 years of service → x + 4y = 1500 → (1)

After 10 years of service → x + 10y = 1800 → (2)

Subtracting, - 6y = - 300

Thus, y = \frac{-300}{-6} =50

Putting y = 50 in x + 4y = 1500

We get, x = 1500 - (4 \times 50) = 1500 - 200 = 1300

Hence, his starting salary = Rs.1300

Fixed Increment = Rs.50
