Correct Answer: 20 : 27
Solution : Given: $\frac{a}{b}=\frac{2}{3}$ ⇒ $\frac{a}{b}=\frac{8}{12}$-----------(i) $\frac{b}{c}=\frac{4}{5}$ ⇒ $\frac{b}{c}=\frac{12}{15}$-----------(ii) From (i) and (ii), we get, ⇒ $a:b:c=8:12:15$ Let $a=8k, b =12k$ and $c=15k$ $\therefore (a+b):(b+c)=(8k+12k):(12k+15k)=20k:27k=20:27$ Hence, the correct answer is 20 : 27.
