The number of students in class A is 25% more than the number of students in class B and the number of students in C is 20% more than the number of students in class A. If the ratio of then number of boys and girls in class A, B and C is 3: 2, 13: 7 and 12: 13 respectively, then the total number of girls in all the classes together is approximately what percent of the total number of students in all the classes together?
ATQ, Let the total number of students in class B = 4x Then, number of students in class A = 5x And number of students in class C = 6x Total number of girls in all three classes = 2/5 of 5x + 7/20 of 4x + 13/25 of 6x = 2x + 7x/5 + 78x/25 = 163x/25 
= 163 ×( 4/15) = 43.46 ~ 43.5%
