As per the given bar graph , we have
Number of girls who ate six or more servings per day = 3 + 3 + 3 = 9
Total number of girls = 72∴ Required percentage = Number of girls who ate six or more servings per day × 100 Total number of girls
Correct Option: A
As per the given bar graph , we have
Number of girls who ate six or more servings per day = 3 + 3 + 3 = 9
Total number of girls = 72∴ Required percentage = Number of girls who ate six or more servings per day × 100 Total number of girls ∴ Required percentage = 9 × 100 = 25 = 12.5% 72 2

On the basis of given graph in question ,
Number of girls ate 2 servings per day = 15
Number of girls ate 1 servings per day = 10
Required number of girls = Number of girls ate 2 servings per day + Number of girls ate 1 servings per dayCorrect Option: C
On the basis of given graph in question ,
Number of girls ate 2 servings per day = 15
Number of girls ate 1 servings per day = 10
Required number of girls = Number of girls ate 2 servings per day + Number of girls ate 1 servings per day
Required number of girls = 15 + 10 = 25
Therefore , Required number of girls is 25 .
