Answer 1

Let us suppose the small number = y and the big number = x.
so, x-y=9
x^2-y^2=981
x^2-y^2=[x+y][x-y]
981=[x+y]*9
[x+y]=981/9
[x+y]=109
now, we have get 2 values
[x+y]=109
[x-y]=9
[x+y]+[x-y]=109+9
2x=118
x=118/2
x=59
[x-y]=9
[59-y]=9
[59-9]=y
so, y=50
So,
the lowest means small number is 50.
the biggest means big number is 59.
