The number of pupils who chose golf, basketball and volleyball is repeated. Make the number of pupils who chose golf, basketball and volleyball the same. LCM of 7 and 5 is 35.
Number of pupils who chose basketball = 7 u
7 u = 84
1 u = 84 ÷ 7 = 12
Number of more pupils who chose golf than canoeing
= 21 u - 10 u
= 11 u
= 11 x 12
= 132
Answer(s): 132
