The number of students who chose squash, jogging and canoeing is repeated. Make the number of students who chose squash, jogging and canoeing the same. LCM of 7 and 5 is 35.
Number of students who chose jogging = 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Number of more students who chose squash than tennis
= 21 u - 10 u
= 11 u
= 11 x 4
= 44
Answer(s): 44
