Question

There are 50 students 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 ?

• A. 39, 29 and 11 respectively
• B. 37, 27 and 11 respectively
• C. 28, 18 and 11 respectively
• D. 21,11 and 29 respectively

Answer 1

The correct option is A 39, 29 and 11 respectively

	Student
English	$21$ (Given in question)
Hindi	$(50-21=29)$
Both Hindi and English	$10$
Total Student	$50$

So, from above table we can see that $29$ students can speak Hindi only and 10 student can speak both Hindi and English. So the total number of students able to speak Hindi will be $29+10=39$.
Thus Hindi speakers will be $39$, only Hindi speakers will be $29$ and only English speakers will $21$.
Option A is the correct answer.
