  • Question
  • 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?


  • Options
  • A. 100 %
  • B. 200%
  • C. 300%
  • D. 600%

  • Correct Answer
  • 200% 

    Explanation

    Let the salaries of A, B, C be x, 2x and 3x respectively.

    Then,2x + 3x = 6000  => x = 1200.

    A's salary = Rs. 1200, B's salary = Rs. 2400, and Cs salary Rs. 3600.
    Excess of C's salary over A's=[ (2400 /1200) x 100] = 200%.
