Question

I am a number less then 3,000 when you divide me by 32 my remainder is 30 what number am I

Answer 1

any number which is 30 more than a multiple of 32. so,
32n+30 < 3000
32n < 2970
n < 92
so pick any number n <92, and 32n+20 will be less than 3000, and leave a remainder of 30 when divided by 32.
