In a school of 100 students each of them play at least one sport among cricket, football, volleyball, basketball, hockey and tennis.It is known that exactly 90 play cricket, 80 play football, 70 play hockey, 60 play basketball , 40 play volleyball and 10 play tennis.

A) What is the maximum number of students who play exactly five of the six games?

40 50 60 70 none of these

B) What is the maximum number of students who play exactly four of six games

60 70 80 50 none of these



drawing lines is very Important, look for Part A, To maximize number of 5s, the limitation is 40% and 10%, we can add them together and increase the limitation to 50%

For part B, 90 and 80 are already highest two, 40 can be added to 60, and 10 can be added to 70, resulting in 90, 80, 80, 80 least of 80%
