Read the row of digits below from left to right.
0 7 5 2 7 0 2 8 8 8 2 0 0 6 2 0 0 8 2 8 2 2 8 4
How many 2s in this row have a digit greater than 5 directly before them?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 4
Check every 2 in the row: the digit before it must be 6, 7, 8 or 9.
Place 4: 5 2 7 — does not count (preceded by 5, which is not greater than 5)
Place 7: 0 2 8 — does not count (preceded by 0, which is not greater than 5)
Place 11: 8 2 0 — counts
Place 15: 6 2 0 — counts
Place 19: 8 2 8 — counts
Place 21: 8 2 2 — counts
Place 22: 2 2 8 — does not count (preceded by 2, which is not greater than 5)
So the answer is 4.
