उत्तर

a. Bar graph of the given data is:


b. On observing the bar graph, we can say that boys like butterscotch the most because the bar for butterscotch in case of boys is of highest length, i.e. 13.

c. Total number of girls = Sum of heights of bars corresponding to girls

= 8 + 12 + 7 + 9 + 10

= 46

d. Number of children who like chocolate flavour = Sum of heights of bars for both boys and girls corresponding to chocolate

= 9 + 12

= 21

e. Total number of children who like strawberry = 3 + 7 = 10

Total number of children who like vanilla = 4 + 8 = 12

∴ Ratio of children who like strawberry flavour to vanilla flavour of ice-cream

= 10 : 12

= 5 : 6
