    Question

    Suppose 6A = 8B = 15C, then find the value of (A:B:C)

    .
    A 22:8:19 Correct Answer Incorrect Answer
    B 20:25:15 Correct Answer Incorrect Answer
    C 21:8:15 Correct Answer Incorrect Answer
    D 20:15:8 Correct Answer Incorrect Answer

    Solution

     Given:

    6A=8B=15C Take the coefficients (6, 8, 15) directly. To find A, B, C individually , invert each coefficient: Now, to clear fractions easily, find the LCM of 6, 8, and 15 (which is 120), and multiply each inverted value by 120:

    Thus: A:B:C=20:15:8 To find A, B, C individually, invert each coefficient:
