How many numbers between 1 and 100 (inclusive) are divisible by 7 or 4?
Every real number is divisible 7 or 4.
100/7=14+
100/4=25
numbers that are divisable by 7 and 4=28,56,84 number =3
So I think the answer is 14+25-3=36
Yes that is true - I was assuming that the question asker was refering only to cardinal numbers. (Positive integers)
And that 'are divisable by 7 or 3' really meant 'are multiples of 7 or 3'
