The number of students who chose volleyball, rugby and basketball is repeated. Make the number of students who chose volleyball, rugby and basketball the same. LCM of 7 and 5 is 35.
Number of students who chose rugby = 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Number of more students who chose volleyball than badminton
= 21 u - 10 u
= 11 u
= 11 x 2
= 22
Answer(s): 22
