The row below, read from left to right, is made up of letters, numbers and symbols.
A 3 2 O # O 5 * % B O # 3 $ 4 Z # A H T * E K R 5 H
If all the symbols are removed from the row, how many numbers in the new row will then have a vowel directly before them?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 3
First remove every symbol and write the new row; then check every number in the new row: the element before it must be a vowel (A, E, I, O or U).
Row without the symbols: A 3 2 O O 5 B O 3 4 Z A H T E K R 5 H
Now check every number of the new row:
Place 2: A 3 2 — counts
Place 3: 3 2 O — does not count (preceded by the number 3)
Place 6: O 5 B — counts
Place 9: O 3 4 — counts
Place 10: 3 4 Z — does not count (preceded by the number 3)
Place 18: R 5 H — does not count (preceded by the consonant R)
So the answer is 3.
