Question and options
50 students were admitted to a Nursery Class. Some students can speak only English and some can speak only Hindi. Ten students can speak both English and Hindi. If the number of students who can speak English is 21, then how many students can speak Hindi, how many can speak only Hindi and how many can speak only English?
- 39,29 and 11 respectively
- 37,27 and 13 respectively
- 28,18,22 respectively
- 21,11 and 29 respectively
Answer and explanation
Correct answer: A - 39,29 and 11 respectively
English = 21 including 10 who speak both, so only English = 11. Hindi = 50 - 11 = 39, and only Hindi = 39 - 10 = 29. So 39, 29 and 11.
