Again apply the same Venn diagram. Since 21 people can speak English (and 10 can speak both), so only English speaking crowd is 11. Total is 50, so only Hindi people will be 50-11 = 39.

Given:
Total students admitted = 50
Number of students who can speak English = 21
Number of students who can speak both English and Hindi = 10

To Find:
Number of students who can speak Hindi, only Hindi and only English

Solution:
Using the formula of sets, we can write:
Total number of students who can speak either Hindi or English = Number of students who can speak only Hindi + Number of students who can speak only English + Number of students who can speak both Hindi and English

Let's plug in the given values:
Total number of students who can speak either Hindi or English = 50
Number of students who can speak only English = 21
Number of students who can speak both Hindi and English = 10

50 = 21 + Number of students who can speak only Hindi + 10

Number of students who can speak only Hindi = 50 - 21 - 10 = 19

Now, we can find the total number of students who can speak Hindi:
Total number of students who can speak Hindi = Number of students who can speak both Hindi and English + Number of students who can speak only Hindi
Total number of students who can speak Hindi = 10 + 19 = 29

Finally, we can find the number of students who can speak only English:
Number of students who can speak only English = 21 - 10 = 11

Therefore, the answer is option D: 39 students can speak Hindi, 29 can speak only Hindi and 11 can speak only English.
