C. Rs. 14000

D. Rs. 15500

Answer: Option A

Solution(By Examveda Team)

Income of A and B
= 2 × 14000
= Rs. 28000
Income of B and C
= 2 × 15600
= Rs. 31200
Income of A and C
= 2 × 14400
= Rs. 28800
Income of A, B and C
$$ = \frac{{\left( {28000 + 31200 + 28800} \right)}}{2}$$
= Rs. 44000
C's income
= 44000 - 28000
= Rs. 16000
