Answer» Correct Answer - Option 4 : 8765001

Concept used :

If the sum of digits of a number is divisible by 3, then the number is also divisible by 3

Calculations :

Sum of digits 

1st option  = 8 + 7 + 0 + 3 + 5 + 4 + 1 = 28

2nd option = 8 + 7 + 0 + 3 + 5 + 9 + 3 = 35

3rd option = 8 + 7 + 0 + 3 + 5 + 7 + 2 = 32

4th option = 8 + 7 + 6 + 5 + 0 + 0 + 1 = 27 

We can check that only 27 is the multiple of 3 

∴ Option 4 is the only option divisible by 3
