Suppose the ratio of Lev's age to Mina's age is 1 : 2 and the ratio of Mina's age to Naomi's age is 3 : 4.

If the sum of all three ages is between 10 and 20, then how old is Mina?

Lev's age = L

Mina's age = M

Naomi's age = N

$$\frac{L}{M}=\frac{1}{2}=\frac{3}{6}$$ => $$\frac{M}{N}=\frac{3}{4}=\frac{6}{8}$$

L = 3a

M = 6a

N = 8a

a = 1

M = 6
