Question
The ratio of number of girls to number of boys is 3 : 2
in a class of 60 students. The average marks scored by the boys in Physics is 72 and the average marks scored by the whole class in Physics is 81. What is the average mark in Physics scored by girls?Solution
Solution -
total student =60
Ratio of the girls and boys=3:2
Girls =3/5) Γ60=36
Boys =24.
Average marks in physics 24 boys =72
Total marks in physics of 24 boys =72Γ24=1728
average marks scored by the whole class in Physics = 81
Total marks scored by whole class =81Γ60=4860
Total marks scored by girls =4860-1728=3132
Average marks in physics of 36 girls=
3132/36=87
