Q159
ReasoningAlphabet, Letter Series & Word Formation
How many meaningful words can be made by changing only the consonants in the word MEAN so that each of the consonants is replaced by the previous letter in the English alphabet, by using each letter only once in each word?
  1. a.One
  2. b.Two
  3. c.Three
  4. d.Four

Answer: (C) Three

In MEAN, the consonants are M and N; replacing each with the previous alphabet letter gives L and M respectively, producing the letter set L, E, A, M. Using each of these letters exactly once, three meaningful English words can be formed: MEAL, LAME and MALE.
