Question
The monthly incomes of Pawan, Qureshi, and Ram are in the
ratio of 4:7:5, while their monthly expenditures are in the ratio of 5:4:8. Pawan earns Rs. 2,800 per month and saves Rs. 800 from his income. Based on this information, determine Ram’s monthly savings.Solution
ATQ;
Let monthly income of ‘Pawan’, ‘Qureshi’ and ‘Ram’ be Rs. ‘4x’, Rs. ‘7x’ and Rs. 5x, respectively.
ATQ;
‘4x’ = 2800
Or, x = 700
So, monthly income of ‘Ram’ = ‘5x = 5 × 700 = Rs. 3,500
Let monthly expenditures of ‘Pawan’, ‘Qureshi’ and ‘Ram’ be Rs. ‘5y’, Rs. ‘4y’ and Rs. ‘8y’, respectively.
Monthly savings of ‘Pawan’ = Rs. 800
ATQ,
(2800 – 5y) = 800
Or, 5y = 2000
So, y = 400
So, monthly expenditure of ‘Ram’ = 8y = 4 × 400 = Rs. 3,200
Therefore, monthly saving of ‘Ram’ = (3500 – 3200) = Rs. 300
