    In a class of 100 students, there are 70 boys whose average marks in a subject are 75. If the average marks of the complete class is 72, then what is the average marks of the girls?   AIEEE  Solved  Paper-2002

    A) 73

    B)                                           65   

    C)           68                              

    D)           74

    Correct Answer: B

    Solution :

                       Since, total number of students = 100 and            number of boys = 70 \[\therefore \]     Number of girls = (100 - 70) = 30 Now, the total marks of 100 students                                                    \[=100\times 72=7200\] and total marks of 70 boys = \[70\times 75=5250\] Total marks of 30 girls = 7200 - 5250 = 1950 \[\therefore \] Average marks of 30 girls \[=\frac{1950}{30}=65\]
