Out of 1800 students in a school, 750 opted basketball, 800 opted cricket and remaining opted table tennis. If a student can opt only one game, find the ratio of:
(a) Number of students who opted basketball to the number of students who opted table tennis.
(b) Number of students who opted cricket to the number of students opting basketball.
(c) Number of students who opted basketball to the total number of students.
(a) It is given in the question that,
Total number of students = 1800
Number of students opted basketball = 750
Also,
Number of students opted cricket = 800
Therefore,
Number of students opted table tennis = Total students – (Number of students opted basketball + Number of students opted cricket)
= 1800 – (750 + 800)
= 1800 – 1550
= 250
Hence,
Required ratio = 
= 
= 
(b) It is given in the question that,
Total number of students = 1800
Also,
Number of students opted basketball = 750
Required ratio = 
= 
(c) It is given in the question that,
Number of students opted basketball = 750
Also,
Total number of students = 1800
Therefore,
Required ratio = 
= 
=
