what is the age of my daughter?
My daughter is twice as old as my son. My wife is three times as old as the sum of the ages of my son and daughter, and I am as old as my wife and my daughter. My mother whose age is the total of all our ages is now 69.
..
let daughter's age be x
son = x/2
wife = 3(x+x/2)
my age= x+3(x+x/2)
mother=(x+x/2)+3(x+x/2)+x+3(x+x/2)=69
..
(x+x/2)(1+3+3)+x=69
7(x+x/2)+x=69
7*3x/2 +x=69
21x/2+x=69
21x+2x /2=69
23x=138
x=138/23
x= 6 daughter's age
