A's Income: 1 Mark
B's Income: 1 Mark
C's Income: 1 Mark
Steps: 1 Mark

Let the income of C = ₹ x
Income of B = ₹ 3x
Income of A = twice of income of B = 2(₹ 3x) = ₹ 6x

Sum of their income
$\Rightarrow 10 x = 72000 \Rightarrow x = ₹ 7200$

Income of C

Income of A
$= ₹ 6 x = ₹ 6 \times 7200 = ₹ 43200$

Income of B
