Question

a man earns a fixed monthly salary and a fixed increments if after 4years his salary was rupee1500 and 10years after ruppes 1800 what was its initial salary​

Answer 1

Step-by-step explanation:

Let the starting salary of the man be Rs. x and the fixed annual increment be Rs. y. Then,

Salary after 4 years of service =Rs. (x+4y)

Salary after 10 years of service =Rs. (x+10y)

∴x+4y=1500 (i)

x+10y=1800 (ii)

Substracting equation (i) from equation (ii), we get

6y=300⇒y=50

Putting y=50 in equation (i), we get x=1300.

Hence the starting salary was Rs. 1300 and annual increment is Rs. 50
