26?

Evenly divided = no remainder left (or zero remainder)

Actually, you're right. 27 is right. I missed to count 150 among the set.

I think it should be 24 because numbers divisible by 15 are added twice.
Numbers divisible by 3 = 17
Numbers divisible by 5 = 11
Number divisible by 15 = 4
So 17+11-4 = 24

Please correct me if I am wrong.

Numbers divisible by 3 start from 102 and end at 150
so total numners are (150-102)/3 + 1 = 17

Numbers divisible by 5 start from 100 and end at 150
So total numbers are (150-100)/5 + 1 = 11

Total Numbers divisible by 15 start from 105 and end at 150
So total numbers are (150-105)/15 + 1 = 4

So 17+11-4 = 24

Opps Sorry

Then the answer is 27 because there 51 numbers from 100-150
