Which of the following number is divisible by 24 ?
A. 35718
B. 63810
C. 537804
D. 3125736
E. None of these
Answer: Option D
Solution(By Examveda Team)
24 = 3 × 8, where 3 and 8 co-primeClearly, 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 × 8), i.e., 24
