Question

please tell according to class 5.​

Answer 1

Step-by-step explanation:

Simple we know that in this chart there are 5 classes

And we know that the sum of all these is 100

so 6B + 20 + 6 + 28 + 36 = 100

6B + 90 = 100

6B = 100-90

6B = 10

so in class 6B has 10 students

a) 6A + 6E = 36 + 28 = 34

b) total no. of students in 6B and 6C = 10 + 20 = 30

out of this 23 are boys

so no. of girls in 6B and 6C = 30-23 = 7

c) there are 100 students
