Answer 1

$<b><i>Hey mate!$

Answer :

============================

19. 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 nth year, his salary be Rs 7000.

Therefore,

aⁿ = a + (n - 1) d

=> 7000 = 5000 + (n - 1) 200

=> (n - 1) 200 = 2000

=> (n - 1) = 10

=> n = 10 + 1

=> n = 11

Therefore, in 11 th year , his salary will be Rs 7000.
