If A/3 = B/2 = C/5, then what is the value of ratio $$(C + A)^{2} : (A + B)^{2} : (B + C)^{2}$$?
Let $$\frac{A}{3}=\frac{B}{2}=\frac{C}{5}=k$$
=> $$A=3k$$ , $$B=2k$$ and $$C=5k$$
To find : $$(C + A)^{2} : (A + B)^{2} : (B + C)^{2}$$
= $$(5k+3k)^2:(3k+2k)^2:(2k+5k)^2$$
= $$8^2k^2:5^2k^2:7^2k^2$$
= $$64:25:49$$
=> Ans - (C)
