Let C's salary be Rs. x

Then,

B's salary $= \frac{80x}{100}$

A's salary

$= ( \frac{50}{100} ) \times ( \frac{80x}{100} )$

$= \frac{40x}{100}$

But given total earnings in a month = $22000$

$x + \frac{80x}{100} + \frac{40x}{100} = 22000$

$x + \frac{120x}{100} = 22000$

$x = 10000$

A's salary

$= 40 \times \frac{10000}{100}$

$= 4000$

Therefore,

Correct option A) 4000
