Question

The ratio of students in class 6A and 6B is 6:11. If 6B has 25 students more than 6A, find
a) Number of students in 6A
b) Number of students in 6B
c) Number of students in 6A: Total students in 6A and 6B.

Answer 1

Answer:

Ratio of students in 6A and 6B =6:11(given)

According to the question

6A/6B=6/11

Let 6A be x

Let 6B be y

or, x/y =6/11

when 6B has 25 more students than 6A

or, 6B =6A + 25

or,y = x+25(as 6B is assumed as y and 6A as x)

by the problem,

x/x+25=6/11

or,11*x=6*(x+25)

or,11x=6x+150

or,11x-6x=150

or,x=30

Students in 6A = 30

therefore students in 6B =x+25=30+25=55

6A:6A+6B=30:55+30=6:17
