Answer 1

Answer:

Rs . 83000

Step-by-step explanation:

Average income of A and B's = 8000

total income of A and B = 8000 × 2 = Rs. 160000

B and C average annual income = 75000

Total income of B and C is 75000 × 2 = 150000

C + A total income is 78000 × 2 = 156000

(A + B) + (B + C) + (C + A) = 160000 = 150000 + 156000

2(A + B + C) = 4.66 lakh

A + B + C = 2.33 lakh

A's income = (A + B + C) - (B + C) = 2.33 - 1.5

= .83 lakh

= 83000
