In a school 85 boys and 35 girls appeared in a public examination . The mean marks of the boys were found to be 40 % whereas the mean marks of the girls were 60% . Determine the average marks % of the school.

Mean marks of boys = 40

no. of boys = 85

sum of marks for boys = 85 × 40 = 3400

Mean marks of girls = 60

no. of girls = 35

sum of marks for girls = 35 × 60 = 2100

Now, total marks obtained by 120 students of the school = 3400 + 2100 = 5500

 

so, average marks %  of the school  =  45.83%
