ANSWER
It can be observed that the incomes that Subba Rao obtained in various years are in A.P. as every year, his salary is increased by Rs 200.
Therefore, the salaries of each year after 1995 are
5000,5200,5400,…
Here, a=5000
d=200
Let after n
th
year, his salary be Rs 7000.
Therefore, a
n
=a+(n−1)d
⇒7000=5000+(n−1)200
⇒200(n−1)=2000
⇒(n−1)=10
∴n=11
Therefore, in 11
th
year, his salary will be Rs 7000.
