Question
Average marks scored by each boy in a class were 85,
whereas that by each girl were 95. If the number of boys is 50% more than the number of girls, then find the average score of each student.Solution
Let the number of girls = 2x.
Thus, the number of boys = 3x. Total marks of boys = 3x × 85 = 255x
Total marks of girls = 2x × 95 = 190x Total marks = 255x + 190x = 445x
Total students = 2x + 3x = 5x Average = 445x ÷ 5x = 89
