If two items of A is equal to three times of B and also equal to four times of C, then A : B : C is : [A]2 : 3 : 5 [B]3 : 4 : 2 [C]4 : 6 : 3 [D]6 : 4 : 3 Show Answer 6 : 4 : 3 ..

If A : B = 2 : 3 and B : C = 4 : 5, then A : B : C is :

If A : B = 2 : 3 and B : C = 4 : 5, then A : B : C is : [A]2 : 3 : 5 [B]5 : 4 : 6 [C]6 : 4 : 5 [D]8 : 12 : 15 Show Answer 8 : 12 : 15 $latex A : B ..
