Question

how many positive numbers less than 300 are divisible by 4 but not by 5

Answer 1

Answer:

60

Step-by-step explanation:

4,8,.....296 divisible by 4

296 = 4+(n-1)4

or n = 74

Now divisible by 5 should be subtracted .

20, 40, ...280

280 = 20+(n-1)20

n= 14

So total will be 74 - 14 = 60
