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.
Answer & explanation
Correct answer: option 2
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
