Lets look at the question in pieces
Number is n comprising of xyz where x is 100th, y is 10 and z is unit digit
function f is defined as f(n) = 2x3y5z
Eg. if n=112 then F(n) = 2(1)*3(1)*5(2)=60
Now if f(m)=9f(v) then what? I am lost after that
I know there must be some way of finding the m and v values isntead of guessing.
