Answer 1

Answer:

So there are 142 + 199 - 28 = 313 numbers divisible by 5 or 7 in the given set of numbers from 0 to 999. The other numbers are not divisible by either 5 or 7. There are 999 - 313 = 686 such numbers. The required number of numbers not divisible by 5 or 7 in the set of numbers from 0 to 999 is 686.
