Answer 1

Answer:

300rs is the answer of question

Answer 2

The initial income is Rs.1000.

Step-by-step explanation:

Let x be the number of years and y be the saresh monthly income.

After 4 years, his income is Rs.1200 and after 11 years, his income is Rs.1550.

His income increased by a constant amount. It means the line passes through (4,1200) and (11,1550).

If a line passes through two points , then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-1200=\dfrac{1550-1200}{11-4}(x-4)$

$y-1200=\dfrac{350}{7}(x-4)$

$y-1200=50(x-4)$

$y-1200=50x-200$

$y=50x-200+1200$

$y=50x+1000$

Substitute x=0 in the above equation.

$y=50(0)+1000=1000$

Therefore, the initial income is Rs.1000.
