Read the row of digits below from left to right.
3 0 3 3 8 6 8 3 8 3 7 4 4 8 9 8 6 0 7 3 8 8 5 0 5 2 8 6
How many 8s in this row have an odd digit directly before them, but do not have 3 directly after them?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 3
Check every 8 in the row: the digit before it must be odd, and the digit after it must not be 3.
Place 5: 3 8 6 — counts
Place 7: 6 8 3 — does not count (preceded by 6, an even digit)
Place 9: 3 8 3 — does not count (followed by 3)
Place 14: 4 8 9 — does not count (preceded by 4, an even digit)
Place 16: 9 8 6 — counts
Place 21: 3 8 8 — counts
Place 22: 8 8 5 — does not count (preceded by 8, an even digit)
Place 27: 2 8 6 — does not count (preceded by 2, an even digit)
So the answer is 3.
