- A 210
- B 25200
- C 2520
- D 302400
Answer & Solution
Correct Answer
(B) 25200
Step-by-step Solution
Detailed explanation
Out of 7 consonants, the number of ways of selecting 3 consonants \(={ }^{7} C_{3}\) Similarly, number of ways of selecting 2 vowels out of 4 vowels \(={ }^{4} C_{2}\) \(\therefore\) Total number of words formed…
