If the number of students who can speak English 21, then how many students can speak Hindi how many can speak only Hindi and how many can speak only English?

Accepted Answer

Here's a brief explanation:

1.  Students who can speak only English:
    Total English speakers = 21
    Students who speak both English and Hindi = 10
    So, students who speak only English = 21 - 10 = 11

2.  Students who can speak only Hindi:
    Total students = 50
    Students who speak only English = 11
    Students who speak both English and Hindi = 10
    Students who speak at least one language = (only English) + (only Hindi) + (both)
    50 = 11 + (only Hindi) + 10
    50 = 21 + (only Hindi)
    Students who speak only Hindi = 50 - 21 = 29

3.  Students who can speak Hindi:
    Students who speak only Hindi = 29
    Students who speak both English and Hindi = 10
    So, total students who can speak Hindi = 29 + 10 = 39

The required values are:
Students who can speak Hindi = 39
Students who can speak only Hindi = 29
Students who can speak only English = 11

Comparing these with the options (Hindi, Only Hindi, Only English):
Option D) 39, 29 and 11 respectively. This matches our calculations.
