Some children went to the cinema, The rest of the children went skating. 66 of these children were girls. 28 of the girls went bowling. 20 of the 36 children who went to the cinema were girls. 15 boys went skating. Work out the number of children who went bowling.​

Answer 1

So, the number of children who went bowling is 97.

Explanation:

Let's break down the information provided:

Total number of children = 120

Number of girls = 66

Number of boys = Total children - Number of girls = 120 - 66 = 54

Now, let's work out the number of children who went to each activity:

Bowling:

Number of girls who went bowling = 28

Number of boys who went bowling = Total who went bowling - Number of girls who went bowling = 120 - 36 (who went to the cinema) - 15 (who went skating) = 69

Cinema:

Number of girls who went to the cinema = 20

Number of boys who went to the cinema = Total who went to the cinema - Number of girls who went to the cinema = 36 - 20 = 16

Skating:

Number of boys who went skating = 15

Now, let's calculate the total number of children who went bowling:

Total who went bowling = Number of girls who went bowling + Number of boys who went bowling = 28 + 69 = 97

So, the number of children who went bowling is 97.
