I came across a perfect riddle earlier today, and it took me a while to figure it out.
Now the question remains: Can you solve it?
Please take a look at the picture below and take your time.
Think about it carefully. Don’t worry, if you can’t find the correct answer, we will show it to you after the picture below.
“One nine” (the digit 9 must be present once)
B. 4819 → Has 4 (O), has 8 (O), has one 9 (O) → Correct!
D. 489 → Has 4 (O), has 8 (O), has one 9 (O) → Correct!
B. 4819 and D. 489 both fit the criteria!
But the more correct answer is D (489). Because there is no comma between ‘one’ and ‘nine.’”
