Let the father's money equals=y
20% of y equals=x
Eldest child got 45% of x
Youngest got 25% of x
Therefore middle will get 100%-(45+25)=100-70=30%
But the middle child got 30% of x=#3000
Therefore 3000=30/100 *x
Making x the subject of the formulae, x =3000*100/30 =1000
Therefore x=#10000
Recall that 20% of y equals=x
Therefore 20% of y equals=#10000
Solving for y:
Making y the subject of the formula
Y =10000*100/20
Y =100000/20
Therefore y equals #50000

  • Zairick: let father income = x
    second son percentage = 100 - (45 + 25) =30%
    and second son share = 3000
    then let total sons share = y
    30/100 * y = 3000
    then y = 10000
    father income =
    20/100 * x = 10000
    then father income = 50000.
