Correct Answer - Option 2 : Rs. 33,600
Given:
Income A : Income B = 4 : 7
Expenditure A : Expenditure B = 1 : 2
Each of them saves Rs. 4,800
Concept Used:
Income = Savings + Expenditure
Saving = Income – Expenditure
Calculation:
Let the income of A and B be 4x and 7x
The expenditure of A and B be y and 2y
⇒ Savings of A = 4x – y ----(I)
⇒ Savings of B = 7x – 2y ----(II)
Saving of A = Saving of B
⇒ 4x – y = 7x – 2y
⇒ y = 3x
Putting the above value in equation I,
⇒ 4x – 3x = 4,800
⇒ x = 4,800
The income of B is 7x,
⇒ 7 × 4,800
⇒ 33,600
∴ The income of B is Rs. 33,600
