Ricky has 420 twitter followers. 180 of them are from singapore and the rest are from the united states. What percentage of us followers more than singapore followers does ricky have?

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4
