### Question 1

The letters of the word 'JOURNEY' have to be arranged such that the vowels come together. How many different ways are possible?

**A**

720.

**B**

730.

**C**

710.

**D**

740.

**Soln.**

**Ans: a**

This word has 7 letters, out of which 4 are consonants and 3 are vowels. The vowels have to occupy three contiguous positions. This triad can be arranged in 3! ways like this: we can place 3 vowels in first place, 2 in second place and 1 in the third place, giving 3 × 2 × 1 = 6 permutations. Next, we have to arrange the 4 consonants and the triad treated as one letter, giving 5! = 120 possibilities. So the total possibilities are 6 × 120 = 720.
