A number with an interesting property:
When I divide it by 2, the remainder is 1.
When I divide it by 3, the remainder is 2.
When I divide it by 4, the remainder is 3.
When I divide it by 5, the remainder is 4.
When I divide it by 6, the remainder is 5.
When I divide it by 7, the remainder is 6.
When I divide it by 8, the remainder is 7.
When I divide it by 9, the remainder is 8.
When I divide it by 10, the remainder is 9.
It's not a small number, but it's not really big, either.
When I looked for a smaller number with this property I couldn't find one.
Can you find it?	Choose the correct choice:	A) 2588	B) 2474	C) 2254	D) 2519	E) 8725
D   2519   The number has to end in 9.   Looked brute force for small numbers.   59 and 119 were promising, but no cigar.   Then looked for agreement among   39 + multiples of 40,   69 + multiples of 70 and   89 + multiples of 90   Smallest one was 2519.
