1. Answer:

   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.
