The sides of a triangle are in the ratio $$\frac{1}{3}:\frac{1}{5}:\frac{1}{6}.$$ If the perimeter is 147 cm, then the length of the smallest side is . . . . . . . .
Answer & Solution
Correct Answer:
Option
D
$$\eqalign{
& {\text{Side ratio}} = \frac{1}{3}:\frac{1}{5}:\frac{1}{6} = \boxed{10:6:5} \cr
& 21\mu \to 147 \cr
& 1\mu \to 7 \cr
& {\text{Smallest side, }}5\mu \to 5 \times 7 = 35 \cr} $$
