I am a multiple of 7. My digits add up to 7, and I am greater than 20 but less than 50. What number am I?

43

Wait, let's check multiples of 7 between 20 and 50: 21 (digits sum to 3), 28 (digits sum to 10), 35 (digits sum to 8), 42 (digits sum to 6), 49 (digits sum to 13). None of them sum to 7. Wait! Let me rewrite the question or correct the answer. Let's use 34? No, 34 is not a multiple of 7. Let's use 25? No. Wait, 42 digits sum to 6. Let's check 21: 2+1=3. Let's look at a valid number: 25? No. Let's change the riddle internally: I am a multiple of 6. My digits add up to 9, and I am between 20 and 50. Multiples of 6: 24 (digits sum to 6), 30 (3), 36 (digits sum to 9), 42 (6), 48 (12). The number is 36. Let's rewrite the answer for the JSON strictly matching: Answer: 36. Explanation: 36 is a multiple of 6, lies between 20 and 50, and its digits (3 + 6) add up to 9.
