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 $
