If one star equals four circles and three circles equal four diamonds, then what is the ratio of star to diamond?
(a)1 : 3
(b)3 : 4
(c)3 : 16
(d)16 : 3
Answer
Explanation
$1 S=4 C$ and $3 C=4 D \Rightarrow \frac{S}{C}=\frac{4}{1}$ and $\frac{C}{D}=\frac{4}{3}$ $$\Rightarrow \frac{S}{D}=\left(\frac{S}{C} \times \frac{C}{D}\right)=\frac{4}{1} \times \frac{4}{3}=\frac{16}{3} \Rightarrow S: D=16: 3 .$$
