Explanation
The correct answer is Option 4 i.e. 3658.
Divisibility rule of 9: A number is divisible by 9 if the sum of its digits is divisible by 9
⇒ 3789 = 3 + 7 + 8 + 9 = 27 [it is divisible by 9]
⇒ 7857 = 7 + 8 + 5 + 7 = 37 [it is divisible by 9]
⇒ 1845 = 1 + 8 + 4 + 5 = 18 [it is divisible by 9]
⇒ 3658 = 3 + 6 + 5 + 8 = 22 [it is not divisible by 9]
Hence, 3658 is not divisible by 9
