The mum is 21 years older than the child. In 6 years from now the mum will be 5 times as old as the child. Question : Where's the father? Try first.....
Solution : The mum is 21 years older than the child. M = C + 21 In 6 years from now the mum will be 5 times as old as the child. M + 6 = (C + 6) x 5
Hence, C + 21 + 6 = (C + 6) x 5 C + 27 = 5C + 30 -3 = 4C C = -3/4
The child is -3/4 years old, it'll be born in 9 months. Right now, the father is on top of the mother.
Amazing huh ?
