James asks 60 pupils which drink they liked best from cola milk and water 32 boys were in the survey 12 of the boys said they liked cola the best 4 boys and 9 girls liked water the best 21 pupils said they liked milk altogether How may students altogether liked cola the best

Students altogether liked cola the best 26

Step-by-step 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
