Wat can be the maximum and minimum number of student in a school

​

Answer 1

Answer:

Maximum students in school = 123

Minimum  students in school = 111

Step-by-step explanation:

Students play chess = A = 60

Students play table tennis = B = 50

Students play carrom = C = 48

Students play games A and C = D = 12

Students play games B and C = E = 15

Students  play games B and A = F = 20

Now

Student playing all the games = G = 12.

We can see easily that

Maximum number of students = A+B+C-D-E-F+G = 60+50+48-12-15-20+12

Maximum number of students = 123

Minimum number of students = (maximum no of students) - G

Minimum number of students = 123 - 12 = 111.

SO

Maximum students in school = 123

Minimum  students in school = 111
