The monthly incomes of Ravi and Shiv are in the ratio 1 : 2 and their monthly expenditures are in the ratio 1 : 3. If each saves ₹4,000 per month, then find the monthly income of Shiv.
Answer & explanation
Correct answer: option 1
Ravi : Shiv
Income 1 : 2
Expenditure 1 : 3
____________________________
Savings = -4000 -4000 (Income - Expenditure)
$\frac{R - 4000}{2R - 4000} = \frac{1}{3}$
Using cross - multiplication method,
⇒ 3R - 2R = (-4000 x 1) - (-4000 x 3)
⇒ R = 8000
Monthly income of Shiv = 2R = ₹ 16,000
