Answer 2

Students altogether liked cola the best 26

Explanation:

Total no of pupils = 60

Boys = 32

girls = 28

we will make a table

Gender cola milk water total

Boys 12 4 32

Girls 9 28

we can find the missing numbers

Let x be for milk

In boys 12 + x + 4 = 32

x = 16

In girls

as 21 liked milk altogether

so girls = 21 - 16 = 5

Gender cola milk water total

Boys 12 16 4 32

Girls 5 9 28

For cola let y

in girls

y + 5 + 9 = 28

y = 14

Gender cola milk water total

Boys 12 16 4 32

Girls 14 5 9 28

Altogether cola = 14 + 12 = 26
