Answer 2

Answer:

Salary in 2003 is Rs. 10,000.

Step-by-step explanation:

Let x be the salary in 2003.

Percentage of increment in salary = 20% per year.

Salary in 2004 = x + 20 % of x = $x+\frac{20x}{100}=\frac{6x}{5}$

Salary in 2005 = 6x/5 + 20 % of 6x/5 = $\frac{6x}{5}+\frac{20}{100}\times\frac{6x}{5}=\frac{6x}{5}+\frac{6x}{25}=\frac{36x}{25}$

According to the question,

$x+\frac{6x}{5}+\frac{36x}{25}=36400$

$\frac{25x+30x+36x}{25}=36400$

$\frac{91x}{25}=36400$

$x=36400\times\frac{25}{91}$

x = 400 × 25

x = 10,000

Therefore, Salary in 2003 is Rs. 10,000.
