    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
