There are 8 consonants and 3 vowels. From 8 consonants, 4 can be selected in 8C4
= 70 ways.
From 3 vowels, 2 can be selected in 3C2
= 3 ways.
Now, to form a word, these 6 ietters (i.e., 4 consonants and 2 vowels) can be arranged in
6P6 = 6! ways.
∴ Total number of words that can be formed
= 70 × 3 × 6!
= 70 × 3 × 720
= 151200
∴ 151200 words of 4 consonants and 2 vowels can be formed.
