Read the row of digits below from left to right.
3 2 5 0 3 1 0 8 4 3 1 6 3 4 5 0 4 6 1 3 7 7 6 3 2
How many digits in this row are greater than both the digit just before them and the digit just after them? (The first and last digits have only one neighbour and are not counted.)
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 6
A digit counts only when it is greater than both its neighbours. Going from left to right, the digits that count are:
5 at place 3 (between 2 and 0)
3 at place 5 (between 0 and 1)
8 at place 8 (between 0 and 4)
6 at place 12 (between 1 and 3)
5 at place 15 (between 4 and 0)
6 at place 18 (between 4 and 1)
Every other digit has a neighbour that is equal to it or greater than it.
So the answer is 6.
