    Answer: (4) (15 : 20 : 24
    Explanation:-
    A : B = 3 : 4    &   B : C = 5 : 6
    Formula-
    A : B = a : b   & B : C = b : c
    Then, A : B : C = ab : bb : bc

    A : B = 3 : 4    &   B : C = 5 : 6
    Then, A : B : C = 3 x 5 : 4 x 5 : 4 x 6
    = 15 : 20 : 24
    Hence, the answer is (4) 15 : 20 : 24.
