Answer: A) 25200
Explanation:
Number of ways of selecting (3 consonants out of 7) and (2 vowels out of 4) = (7C3*4C2)
= 210.
Number of groups, each having 3 consonants and 2 vowels = 210.
Each group contains 5 letters.
Number of ways of arranging 5 letters among themselves = 5! = 120
Required number of ways = (210 x 120) = 25200.
