Which of the following statements regarding arrangement of the word ‘RIYADH’ is/are true: i. Two vowels can be arranged together in 120 ways ii. Vowels do not occur together in 240 ways Which of the above statements are true?
Explanation:
(i) Two vowels can be arranged together in RIYADH in 5! × 2! = 240 ways Hence, statement (i) is not true.
(ii) Total arrangements where vowels are not together = total arrangements possible – arrangements where vowels are together = 6! – 240 = 720 – 240 = 480
Hence, statement (ii) is also not true.
Hence, option (d).
