Read the row of digits below from left to right.
0 3 9 6 4 7 8 8 0 1 6 1 3 9 1 2 1 9 0 2 2 9 0 6 6 0
How many odd digits in this row have a smaller digit directly before them and a larger digit directly after them?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 4
Check every odd digit (1, 3, 5, 7, 9) in the row: the digit before it must be smaller than it, and the digit after it must be larger than it.
Place 2: 0 3 9 — counts
Place 3: 3 9 6 — does not count (6 after it is not larger than 9)
Place 6: 4 7 8 — counts
Place 10: 0 1 6 — counts
Place 12: 6 1 3 — does not count (6 before it is not smaller than 1)
Place 13: 1 3 9 — counts
Place 14: 3 9 1 — does not count (1 after it is not larger than 9)
Place 15: 9 1 2 — does not count (9 before it is not smaller than 1)
Place 17: 2 1 9 — does not count (2 before it is not smaller than 1)
Place 18: 1 9 0 — does not count (0 after it is not larger than 9)
Place 22: 2 9 0 — does not count (0 after it is not larger than 9)
So the answer is 4.
