Question

Sons age is 5 times daughters. mother is five times son. father is 5 times wife. total of all age is grandpas who is celebrating 81st b`day.

Answer 1

let daughter age= x year
brother age is 5x
mother age is 5(5x)=25x
father age is 25x(5)= 125x
ATQ,
x+5x+25x+125x=81
156x=81
x=0.52
daughter age = 0.52*12= 6.24 months
brother age is 5*0.52 =2.6 years
mother age is 5*2.6= 13 year
father age is 5*13= 65.
This is funny question because of mother age but interesting...
