Question

From first 500 positive integers which are not 2 nor by 3 and nor by 5

Answer 1

Step-by-step explanation:

Total number which are divided by 3 between 1 to 500 is 166.

The divisibility rule of 6 is those numbers which are divided by 2 and 3 both are divisible by 6 . So first we have to divide 166 by 2 . 166÷2=83.

Again we have to divide 166 by 5. Therefore if we divide 166 by 5 ,then the quotient is 33.

Hence the actual result is 166-(83+33)=50.

Answer 2

357 are not divisible by them and 212 are exactly divisible by one of them
