Each vowel in the word PLUMBER is changed to the letter immediately following it in the English alphabetical order and each consonant is changed to the letter immediately preceding it in the English alphabetical order. How many vowels are there in the group of letters thus formed?
2
In PLUMBER the vowels are U and E; the consonants are P, L, M, B and R. Vowels move one letter forward and consonants move one letter backward.
P → O, L → K, U → V, M → L, B → A, E → F, R → Q.
| Original | P | L | U | M | B | E | R |
| New | O | K | V | L | A | F | Q |
The new group is OKVLAFQ. Its vowels are O and A, so there are 2 vowels.
Check: the other new letters K, V, L, F and Q are all consonants, and each of the seven letters was changed exactly once (two vowels forward, five consonants backward).
Hence, 2.
