The following table gives the data regarding the number of students studying in various streams in various universities(X,Y& Z) in the year 2017.

Note: Total students=Male students+ Female students
1. Total number of students studying in Psychology in X and Y is what percent less than that of those studying in Chemistry in the same university?

Ans:5
Total number of students studying in Psychology in X and Y=2200+2600=4800
Total number of students studying in Chemistry in X and Y=2800+2400=5200
Required percentage= [(5200-4800)/5200]*100
=100/13
= 7 9/13%

 

2. The number of female students studying in stream Chemistry in Z is what percent of the number of female students in Psychology in X?

Ans:4
Number of female students studying in Chemistry in Z= 2200-1900=300
Number of female students in Psychology in X=2200-1500=700
Required percentage= (300/700)*100=300/7=42 6/7%

 

3. What is the ratio of the total number of males studying in stream physics and chemistry in Y University to the total number of males studying in the same stream in Z?

Ans:2
Total number of males studying in physics and chemistry in Y University=2200+1800=4000
Total number of males studying in physics and chemistry in Z University=2500+1900=4400
Required ratio=4000:4400=10:11

 

4. Total number of females studying in stream English in all the university together in 2018 was 2190 more than that in the year 2017.

Total students in English in 2018=3000*(7/4) =5250

 

5. What is the average number of female students studying in Physics in all the given university?

Ans:2
Number of female students studying in Physics in X university=4000-2800=1200
Number of female students studying in Physics in Y university=3800-2200=1600
Number of female students studying in Physics in Z university=3000-2500=500
Average number of female students studying in Physics in all the given university=(1200+1600+500)/3
=3300/3
=1100

 

Set-62
Read the following passage carefully and answer the given questions.
In college, students like three different computer courses C, C++ and Java. The number of students who like all the three languages is 20 which is 1/29th of the total students.  Ratio of the number of students who likes only C, C++ and Java is 4: 8: 7. Ratio of the number of students who likes C and C++, C++ and Java and C and Java is 2: 4: 3. Number of students who likes only C is equal to the number of students who likes C++ and Java which is 80.
6. Number of students who likes Only Java is what percentage of the total students in the college?

Ans:3
Total students = 20 * 29 = 580

 


Required percentage = (140/580)* 100 =24.14%

 

7. Find the ratio of the number of students who likes C to the number of students who likes C++.

Ans:2
Total students = 20 * 29 = 580

 


Required ratio = (80+40+20+60): (160+80+40+20)
= 200: 300
= 2:3

 

8. Number of students who likes only Java is what percentage more/less than the number of students who likes only C++?

Ans:4
Total students = 20 * 29 = 580

 


Required percentage = [(160-140)/160] * 100
= (20/160) * 100
= 12.5%

9. Find the difference of the number of students who likes C++ and Java to the number of students who likes C and Java

Ans:5
Total students = 20 * 29 = 580

 


Required difference = 80 – 60 = 20

 

10. Find the total number of students who likes at least two courses.

Ans:2
Total students = 20 * 29 = 580
