Answer 2

Answer:

Since positive integers are<100,so all integers are two digit number except 7.

Now integers are not divisible by 2 & 5 then,

Integers ends with 0,2,4,5,6,8 will not include.

Again integers which are multiple of 3 will not include so the integers are

{7,11,13,17,19,23,29,31,37,41,43,47,49,53,59,61,67,71

73,77,79,83,89,91,97}

Therefore 25 positive integers not greater than 100 are not divisible by 2,3 or 5.
