Show Answer
Answer:
Correct Answer: C
Solution:
- We know that,
Numbers divisible by 4 and 6 will be multiples of the LCM of 4 and 6 i.e. 12.
Now, numbers from 1 to 600 divisible by 12
$ =\frac{600}{12}-1=49 $ (minus 1 because 600 is excluded)
Now, numbers divisible by 12 from 1 to $ 100=\frac{100}{12}=8 $
$ \therefore $ Numbers divisible by 12 between 100 and 600
$ =49-8=41 $
