d:dog, c:cat, r:rat  d+r=20...(i)  c+r=10...(ii)  d+c=24...(iii)  (i)+(ii)+(iii):  2(d+c+r)=20+10+24=54  d+c+r=((54)/2)=27
$${d}:{dog},\:{c}:{cat},\:{r}:{rat} \\ $$$${d}+{r}=\mathrm{20}…\left({i}\right) \\ $$$${c}+{r}=\mathrm{10}…\left({ii}\right) \\ $$$${d}+{c}=\mathrm{24}…\left({iii}\right) \\ $$$$\left({i}\right)+\left({ii}\right)+\left({iii}\right): \\ $$$$\mathrm{2}\left({d}+{c}+{r}\right)=\mathrm{20}+\mathrm{10}+\mathrm{24}=\mathrm{54} \\ $$$${d}+{c}+{r}=\frac{\mathrm{54}}{\mathrm{2}}=\mathrm{27} \\ $$
