Identify the number which does NOT satisfy: Sum of digits is a factor of the number.

1. 24
2. 36
3. 42
4. 39

Correct answer: 39

Solution

For 24, the sum of digits is 6 and 24 is divisible by 6. For 36, the sum is 9 and 36 is divisible by 9; for 42, the sum is 6 and 42 is divisible by 6. For 39, the sum is 12, and 39 is not divisible by 12, so it does not satisfy the condition.
