Answer 2

Answer:

Step-by-step explanation:

       Given: The number of letters in the word DELHI = 5

we know that the number of vowels in the given word DELHI are E,I = 2

And the number of even places which these vowels can occupy are 2 (second and fourth)

Thus the number of ways to arrange vowels in the even places= 2p2

And the number of ways to arrange the remaining 3 letters in 3 places =3p3

So the total number of ways   =  2p2*3p3=12
