Tip :
Divisibility by 3
• If sum of the digits of the given number is divisible by 3, then the number is also divisible by 3.
________________________
Option A ( 8003 )
Let's see whether the sum of the digits of the given number is divisible by 3 or not.
→ 3 + 0 + 0 + 8
→ 3 + 8
→ 11
Since 11 is not divisible by 3, then 8003 will also be not divisible by 3.
Option B ( 6896 )
Let's see whether the sum of the digits of the given number is divisible by 3 or not.
→ 6 + 8 + 9 + 6
→ 14 + 15
→ 29
Since 29 is not divisible by 3, then 6896 will also be not divisible by 3.
Option C ( 4878 ) ✔
Let's see whether the sum of the digits of the given number is divisible by 3 or not.
→ 4 + 8 + 7 + 8
→ 12 + 15
→ 27
Since 27 is divisible by 3, then 4878 will also be not divisible by 3.
Option D ( 2690 )
Let's see whether the sum of the digits of the given number is divisible by 3 or not.
→ 2 + 6 + 9 + 0
→ 8 + 9
→ 17
Since 17 is not divisible by 3, then 2690 will also be not divisible by 3.
