All the letters of the word' ABRACADABRA' are arranged in different possible ways. Then the number of such arrangements in which the vowels are together is
- A 1200
- B 1240
- C 1220
- D 1260
Answer & Solution
Correct Answer
(D) 1260
Step-by-step Solution
Detailed explanation
The word ABRACADABRA has
A: 5 times, B: 2 times, R: 2 times, C, D: 1 time each When all vowels are together, we have to arrange 7 elements. \(\therefore\) No. of arrangements \(\frac{7 !}{2 ! 2 !}=1260\)
