Read the row of digits below from left to right.
7 9 4 9 9 0 9 2 9 0 9 9 0 8 1 9 5 9 0 9 0 3 9 1 1 8 7
How many 9s in this row have 0 directly after them?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 5
Check every 9 in the row: the digit after it must be 0.
Place 2: 7 9 4 — does not count (followed by 4)
Place 4: 4 9 9 — does not count (followed by 9)
Place 5: 9 9 0 — counts
Place 7: 0 9 2 — does not count (followed by 2)
Place 9: 2 9 0 — counts
Place 11: 0 9 9 — does not count (followed by 9)
Place 12: 9 9 0 — counts
Place 16: 1 9 5 — does not count (followed by 5)
Place 18: 5 9 0 — counts
Place 20: 0 9 0 — counts
Place 23: 3 9 1 — does not count (followed by 1)
So the answer is 5.
