Answer to Question #301088 in Algebra for BIGIRIMANA Elie

Question

A girl is 9 years old. Her brother is 4 years older. Their mother is 4 times older than her brother. Their father is years older than the mother. How old is the father?

Answer 1

Girl $=$ 9years

Brother $=(9+4)years$

$=13years$

Mother $=$ four times older than brother(son)

$=(4\times13)years$

$=$ 52years

Father $=(52+y)years$

NB*. They have not specified the number of years that the father(husband) is older than the mother(wife). So we have assumed that the father(husband) is y-years older than the mother(wife).
