Question

In a school, the ratio of students who like Computer but not Social study and thestudents who like Social study but not Computer is 7:5 and the ratio who don't like both subjects and like both subjects is 3 : 5. If 60% of students like both subjects and 60 students like only one of the subjects then, find the number of students in the school.​

Answer 1

Let the total number of students in the school be x.

Then, (7/12)x + (5/12)x = 60

=> (12/12)x = 60

=> x = 60

Hence, the total number of students in the school is 60.
