Question
The monthly incomes of Vishal and Rahul are in the ratio
7:6. Their combined monthly income is Rs. 6500. Rahul's monthly savings are Rs. 1200, and Vishal's monthly expenditure is 20% more than Rahul's. Find Vishal's monthly savings.Solution
Let the monthly income of Vishal and Rahul be Rs. 7x and Rs. 6x respectively.
So, 7x + 6x = 6500
13x = 6500
x = 500
So, monthly income of Vishal = 7x = Rs. 3500
Monthly income of Rahul = 6x = Rs. 3000
Monthly expenditure of Rahul = 3000 – 1200 = Rs. 1800
Monthly expenditure of Vishal = 1.2 × 1800 = Rs. 2160
So, monthly savings of Vishal = 3500 – 2160 = Rs. 1340
