Question:
DIRECTION: Study the pie–chart carefully and answer the questions based on it.


Percentage of student enrolled in different game classes in a school

Total number of student = 3600


What is the ratio of the number of students enrolled in Tennis and Basket ball classes together to the number of students enrolled  in Running classes?
Options:
A) 3 : 1
B) 4 : 7
C) 7 : 5
D) 3 : 5
Solution:

Solution: (A)

Students enrolled in Tennis class

= \(\cfrac{64.8^o}{360^o}\)  × 3600 = 648

Students enrolled in Basketball class 

= \(\cfrac{21}{100}\)  × 3600 = 756

Student enrolled in Running class 

= \(\cfrac{46.8^o}{360}\) × 3600 = 468

Required ratio = (648 + 756) : 468 = 1404 : 468 = 3 : 1
