Question

in a class of 52 students the number of boys is 6 by 7 of the girls find the number of boys and girls in the class​

Answer 1

Answer:

Step-by-step explanation:

Let Boys be 6x

Girls be 7x

Total student = 6x + 7x = 52

13x = 52

x= 52/13 = 4

Therefore,

Girls  = 6 X 4 = 24

Boys = 7 X 4 = 28

Answer 2

Answer:

No. of boys(x)=24

No of girls(y)=28

Step-by-step explanation:

equations:- x+y=52 ---- eq.1

x=6/7y -------- eq .2

therefore 6/7y+y=52

7y+6y/7=52

therefore 13y/7=52

y=52×7/13

therefore y=28

substitute y=28 in eq. 2

x=6/7×28

therefore x=24
