Darien Newman · Answer 1

Cycling = 69 - (32 + 27) = 69 - 59 = 10

Badminton = 62 - (32+28) = 62 - 60 = 2

Archery = 63 - (27 + 28) = 63 - 55 = 8

Total for 1 sport = 10 + 2 + 8 = 20

Pupils left = 120 - 20 = 100

Pupils that picked two sports = 27 + 28 + 32 = 87

Number of pupils to pick all sports = 100 - 87 = 13

13 pupils picked all three
