Directions: The next three items are based on a survey on occurrence of vowels in a certain book irrespective of whether they are in upper or lower case.
Vowel: A=20%, E=45%, I=15%, O=8%, U=12%
If "O" and "U", irrespective of upper or lower case, occur exactly 5040 times, then how many times does the letter "E" occur in the book in the upper or the lower case?

- A11840
- B11600
- C11430
- D11340
Explanation
O and U together account for 8 + 12 = 20 percent of all vowel occurrences. Since 20 percent equals 5040, the total number of vowels is 5040/0.20 = 25200. The letter E, at 45 percent, occurs 0.45 x 25200 = 11340 times. Hence option D.
