First, I should point out that g(x) should be written as g(x)=(x+2)/3, otherwise the problem is confusing.

(A) 
(B) Since
and
, it holds that
for all x. This means the composed functions are *identical*

Answer:
1 Employee gets = Rs 13,020
Step-by-step explanation:
25% profit = Rs 26,04,000
Bonus is always 20% of the profit
So, Bonus:
=> 26,04,000/5
=> Rs 520,800
50% bonus from the profit = 520,800/2
=> Rs 260,400
This was divided equally among 20 employees.
<u><em>So, Each Employ gets:</em></u>
=> 1 Employee = 260,400/20
=> 1 Employee gets = Rs 13,020
