Correct Answer - Option 2 : 3 : 4 : 6
Given:
Income ratio = 3 : 5 : 12
Expenditure ratio = 1 : 2 : 6
C's savings = 1/4 of income
Calculation:
Let the incomes be 3x, 5x, 12x
and expenditure be y, 2y, 6y
A.T.Q
12x - 6y = 1/4 × 12x
⇒ 9x = 6y
⇒ x : y = 2 : 3
Income = 6 ratio, 10 ratio, 24 ratio
Expenditure = 3 ratio, 6 ratio, 18 ratio
Savings = (6 - 3) : (10 - 6) : (24 - 18)
⇒ 3 : 4 : 6
∴ The answer is 3 : 4 : 6
