Answer:
his salary will be Rs 7000.
Step-by-step explanation:
The annual salary received by Subba Rao in the years 1995,1996,1997..... is 5000, 5200, 5400,...... 7000
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, …
Given:
a = 5000
d = 200
Let after nth year, his salary be Rs 7000.
an = a + (n − 1) d
7000 = 5000 + (n − 1) 200
200(n − 1) = 2000
(n − 1) = 10
n = 11
Thus in 11th year, his salary will be Rs 7000.
