To try to make sense of the riddle I took "The number of my hundreds and the number of my thousands is 3." to be "The number of my hundreds plus the number of my thousands is 3." I think it might be 127x, where x is anything other than 1, 2 or 7. The number of the thousands is 1, the number of the hundreds is 2, so the number of the thousands plus the number of the hundreds is 3. The number of the tens is 7, which is 7 times the number of the thousands. Stephen at Math Central.
