Solution

The correct option is B 1000
Let the total number of students in the school be x
Then Number of girls 3x7
Number of boys x3x7=4x7
Number of boys below ten years of age 14×4x7=x7
Number of girls below ten years of age 56×3x7=5x14
Total number of students below 10 years of age x7+5x14=7x14=x2
Total number of students above 10 years of age xx2=x2
Given x2=500x=1000
