Question

How many different ways can you find 2 positive integers that sum to 1000, where one is divisible by 7 and the other is divisible by 11?

Answer 1

Answer:

The number of integers divisible by 5 from 1 to 1000 is 1000/5 = 200. The number of integers divisible by 2 AND 5 from 1 to 1000 is 1000/lcm(2,5) = 1000/10 = 100. So your answer is 400 integers.
