Solution and Answers :



1.5

Girls in School T = 1500

Total number of students in School Q = 3500+2000=5500

Ratio = 1500 : 5500 = 3:11


2.4

Boys in School S = 4500

Boys in School Q = 3500

==> percentage of Boys from school S in Boys in School Q = (4500*100)/3500=128.57~=129%


3.1

Total number of boys from all schools = 5500+3500+3000+4500+4000=20500

Average number of boys = 20500/5 = 4100


4.5

100 students increased . But here not mentioned number of girls and boys in the number of  100 students.

Data insufficient


5.2


Total number of girls in P, Q and R = 2500+2000+1500= 6000

Total number of boys in R, S and T = 3000+4500+4000=11500

Ratio = 6000 : 11500 = 12:23
