For integers m,n such that ( 0 <= n < m )
How many positive integers are inexpressible as ( 3m + n ) ?
How many positive integers are inexpressible as ( 5m + n ) ?
How many positive integers are inexpressible as ( 10m + n ) ?

i suppose... Some ppl can do this (in their heads) within 20 seconds.
Do we have this type of a problem (or (gap) shape)
in a real math problem, or real physics / engineering problem ?
