Quantity I: In class A ratio of number of boys and girls are on the ratio 5: 4.If 20% of the boys and 25% of the girls were removed respectively, and 20 boys were added then the ratio of number of boys to number of girls in the ratio 2: 1. Find the total number of students in class A initially.
Quantity II: In class B the number of boys in class B is x and the number of girls in the class is (x - 20). The average weight of the boys and girls is 50 kg and 20 kg respectively. Then the average weight of the whole class is 37.5 kg. Find the Total number of students in Class B
