In a class there are 26 boys and 24 girls. The Math teacher administered a test and found that the average score of the whole class is 85.If the average score of the boys was 82, find the average score of the girls.

Options:

88.25

85

87.5

Correct Answer:

88.25

Explanation:

Total students = 50

Sum of marks of whole class = 50 x 85 = 4250

Sum of marks of boys = 26 x 82 = 2132

Sum of marks of girls = 4250 - 2132 = 2118

Average marks of girls = \(\frac{2118}{24}\) = 88.25
