total amount left = $120,000
He has 2 children and 8 grand children.
let
x = amount each grand children will get
amount the each children will get = 2x
Therefore,
[tex]\begin{gathered} 2x(2)+8x=120,000 \\ 4x+8x=120,000 \\ 12x=120,000 \\ x=\frac{120,000}{12} \\ x=\text{ \$1000}0 \end{gathered}[/tex]The amount each children got = 2(10000) = $20,000
The amount each grand children got = $10,000
