Question

If A : B = 3:4 B:C = 5:2. Then find the value of A:B:C

Answer 1

Answer: 15:20:28

Step-by-step explanation:

A : B = 3 : 4 & B : C = 5 : 2
Let A = 3X and B = 4X
Similarly Let B = 5Y and C = 2Y

⇒ $4X=5Y$
⇒$Y=4X/5$

∴ A : B : C =  $3X:4X:7(4X/5)$ = $15X:20X:28X$
∴ Required Ratio A : B : C = 15 : 20 : 28
