The salaries of A, B, and C are in the ratio of 1 : 2 : 3. The salary of B and C together is Rs. 6000. By what percent is the salary of C more than that of A?

Let the salaries of A, B, C be x, 2x and 3x respectively. Then,2x + 3x = 6000 => x = 1200. As salary = Rs. 1200, Bs salary = Rs. 2400, and Cs salary Rs. 3600. Excess of Cs salary over As=[ (2400 /1200) x 100] = 200%.
