Jan is x years old, her sister is twice as old as her, and her brother is three times older than her. Their ages add up to 29. H

victus00 [196]

Jan's age = $4\frac{5}{6}$ years

Sister's age = $9\frac{2}{3} \: years$

Step-by-step explanation:

Jan's age = x years

Sister's age = 2x years

Brother's age = 3x years

According to the given condition:

x + 2x + 3x = 29

6x = 29

x = 29/6

x = $4\frac{5}{6}$ years

2x = $2\times \frac{29}{6}= \frac{29}{3}=9\frac{2}{3} \: years$

Therefore,

Jan's age = $4\frac{5}{6}$ years

Sister's age = $9\frac{2}{3} \: years$
