Problema Solution
A mother is 9 times the age of her daughter in 30 years time she will be twice the age of her daughter how old are they now
Answer provided by our tutors
let
m = the age of the mother now
d = the age of the daughter now
a mother is 9 times the age of her daughter
m = 9d
in 30 years time she will be twice the age of her daughter
m + 30 =2(d + 30)
by solving the system of equations
m = 9d
m + 30 =2(d + 30)
we find
d = 30/7 = 4 2/7 years
m = 270/7 = 38 4/7 years
