You need to find the ratios that will give the same answer. For example for the second one
$$\frac{c}{r}$$

You have the same side as ratio from both triangle so does that mean
$$\frac{a}{p}$$
also has the same side and if it does that means the ratio will be the same

since ACB and PRQ are similar.$$\frac {AC}{PR}=\frac {CB}{RQ}=\frac {AP}{PQ}$$
Now you can get the ans. by substitiuting the value.
