  • Question
  • If P : Q : R = 2 : 3 : 4, then find P/Q : Q/R : R/P?


  • Options
  • A. 8 : 9 : 24
  • B. 9 : 8 : 24
  • C. 24 : 8 : 9
  • D. 8 : 24 : 9

  • Correct Answer
  • 8 : 9 : 24 

    Explanation

    Given that, P : Q : R = 2 : 3 : 4
    Let P = 2K, Q = 3K, R = 4K
    ? P/Q = 2K/3K = 2/3,
    Q/R = 3K/4K = 3/4,
    R/P = 4K/2K = 2/1
    ? P/Q : Q/R : R/P = 2/3 : 3/4 : 2/1
    = (2 x 12)/3 : (3 x 12)/ 4 : (2 x 12)/1
    = (2 x 4) : (3 x 3) : 24
    = 8 : 9 : 24
