Question
The monthly incomes of Sarah and David are in the ratio
5:6, respectively, and the respective ratio of their savings is 1:2. If the monthly savings of Sarah are exactly the same as the monthly expenditure of David, what percentage of Sarah's income does she spend, and how does that compare to the percentage of David's income he spends?"Solution
ATQ, Let the monthly savings of Saraha and David be Rs. x and Rs. 2x, respectively. So, the monthly expenditure of David = Rs. x So, the monthly income of David = 2x + x = Rs. 3x Monthly income of Saraha = 3x Γ 5/6 = Rs. 2.5x Monthly expenditure of Saraha = 2.5x β x = Rs. 1.5x So, the desired percentage = (1.5x β x)/x Γ 100 = 50%
