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.

Total number of students = 1800, Number of students opted basketball = 750
Number of students opted cricket = 800
Therefore, number of students opted tennis = 1800 – (750 + 800) = 250
(a)Ratio of students opted basketball to that of opted table tennis=750/250=3/1=3:1
(b)Ratio of students opted cricket to students opted basketball= 800/750=16/15=16:15
(c)Ratio of students opted basketball to total no. of students= 750/1800=5/12=5:12
