One year ago, the ratio between A's and B's salary was 4:5. The ratio of their individual salaries of last year and present year are 3:5 and 2:3 respectively. If their total salaries for the present year is Rs 6800, the present salary of A is
Answer: B Ratio of A's last year and present year salary = 3:5 Let salary be 3x and 5x respectively. Ratio of B's in last year and present year salary = 2:3 Let salary be 2y and 3y respectively. Given that, 3x/2y = 4/5 => 15x = 8y.............(i) Also, given that, 5x+3y = 6800............(ii) From equation (i) and (ii), we get y = 1200 and x = 640. A's present salary = 5x = 5*640 = 3200.
Q. No. 20:
Shyam, Gopal and Madhur are three partners in a business. Their capitals are respectively Rs 4,000, Rs 8,000 and Rs 6,000. Shyam gets 20% of total profit for managing the business. The remaining profit is divided among the three in the ratio of their capitals. At the end of the year, the profit of Shyam is Rs 2200 less than the sum of the profit of Gopal and Madhur. How much profit, Madhur will get ?
Answer: B The ratio of profit of Shyam, Gopal and Madhur is 2:4:3. Let the annual profit be p. Them Shyam will get 0.2p. And, remaining 0.8p will be distributed in the ratio of their capital. Given, [7/8 * (0.8p)] - [2/9 * (0.8p)] - 0.2p = 2200. => p = 9,000 Madhur's share = 0.8 * 9000/3 = Rs 2400.
