The simplest and quickest way to solve this is below-
Take f(v) as a value containing factors 2,3,5 which will crate 3 digit integer.
Assume f(v) as value 100 or 150 or 200 anything.
For explanation below, consider f(v) as value 200.
f(v)=200 =2^3 * 3^0 * 5^2
so, v=302
similarly f(m)=9f(v)= 2^3 * 3^2 * 5^2
so, m=322
m-v=322=302=20
