Correct Answer: 103. (2)

Solution: 103. (2) $a: b=4: 5 ; $

$\mathrm{b}: \mathrm{c}=10: 9$

$\therefore \frac{a}{b} \times \frac{b}{c}=\frac{4}{5} \times \frac{10}{9} \Rightarrow \frac{a}{c}=\frac{8}{9}$

$\Rightarrow \frac{a}{c}+1=\frac{8}{9}+1$

$\Rightarrow \frac{a+c}{c}=\frac{8+9}{9}=\frac{17}{9}$
