Read the row of digits below from left to right.
7 5 8 5 6 5 7 2 2 9 1 8 5 9 8 5 4 9 4 8 5 8 2 4
How many 5s in this row have 8 directly before them?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 4
Check every 5 in the row: the digit before it must be 8.
Place 2: 7 5 8 — does not count (preceded by 7)
Place 4: 8 5 6 — counts
Place 6: 6 5 7 — does not count (preceded by 6)
Place 13: 8 5 9 — counts
Place 16: 8 5 4 — counts
Place 21: 8 5 8 — counts
So the answer is 4.
