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 number of students who opted basketball to the number of students who opted table tennis.
उत्तर
Given,
Number of students in the school = 1800
The number of students who opted for basketball = 750
The number of students who opted for cricket = 800
The number of students who opted for table tennis = 1800 – (750 + 800) = 1800 – 1550 = 250
Ratio of the number of students who opted for basketball to the number of students who opted for table tennis
= `750/250 = 3/1`
