Which of the following number is divisible by 24 ?
Answer: Option
Explanation:
24 = 3 x8, where 3 and 8 co-prime.
Clearly, 35718 is not divisible by 8, as 718 is not divisible by 8.
Similarly, 63810 is not divisible by 8 and 537804 is not divisible by 8.
Consider option (D),
Sum of digits = (3 + 1 + 2 + 5 + 7 + 3 + 6) = 27, which is divisible by 3.
Also, 736 is divisible by 8.
3125736 is divisible by (3 x 8), i.e., 24.

537804 is divisible by 2, 3, 4.
So 537804 is also divisible by 24 na?
If 537804 /24, the remainder will be 0. So the answer will be c and d.
Can anyone clear my doubt?

Hi Reddy :
They took 8 and 3 because 3*8=24 any number divisible by 24 should be divisible by its divisors
You can also take 4*6

Hell friends, I did not get why your dividing total number with 8 and sum of total numbers with 3 and on what basis your selecting 8 for dividing total number and on what basis your selecting 3 for dividing sum of total number.
Can anybody explain me?
