    Solution

    We can say that Let monthly income of Vicky and Vinnay be Rs. 7x and Rs. 9x, respectively. ATQ, (7x –6200)/(9x – 7800) = 3/4 28x – 24800 = 27x – 23400 x = 1400 Savings of Vicky = 7x – 6200 = 9800 – 6200 = Rs. 3600 Savings of Vinnay = 9x – 7800 = 12600 – 7800 = Rs. 4800 Hence Required difference = 4800 – 3600 = Rs.1200
