Correct Answer: $64:25:49$
Solution :
Given: $\frac{A}{3}=\frac{B}{2}=\frac{C}{5}$
Let $\frac{A}{3}=\frac{B}{2}=\frac{C}{5}=k$
$⇒A=3k,B=2k,C=5k$
Putting these values, we get,
$(C+A)^{2}:(A+B)^{2}:(B+C)^{2}$
$=(5k+3k)^{2}:(3k+2k)^{2}:(2k+5k)^{2}$
$=64k^{2}:25k^{2}:49k^{2}$
$=64:25:49$
Hence, the correct answer is $64:25:49$.
