2) Find number of boys and girls if total strength of the school is d.
1. 120 2. 70
1. 120 2. 7O
70 boys and total is 120
1. Boys : Girls ratio is 7:5 that is 7:5 = x:50 , step1 7*50 = 5x, step2 350= 5x, step 3 x= 350/5, step 4 x= 70, so total number of boys is 70, 70+50= 120
total=12*50/5=120, boys=120-50=70 , boys=d*7/12 , girls=d*5/12
let the ratio as 5x,7x. girls ratio is 5x=50. x=50/5=10. boys=7×10=70. 70+50=120.

Hey there!
Given ratio of boys and girls = 7 : 5 .
Case 1 :
Number of girls = 50 .
But we know that, Number of girls = 5/(7+5)* Total number of students .
5/12 * Total students = 50 .
Let the Total students = x.
5/12x = 50
x = 10*12
x = 120 students. [ Answer ]
Case 2 :
I guess this question is " Find number of boys and girls if total strength of the school is " d "
Ratio between boys & girls = 7 : 5 .
Total ratio = 7 + 5 = 12 .
Number of boys = 7/12 * Total number of students = 7/12d .
Number of girls = 5/12 * Total number of students = 5/12d.
Case 3 :
The strength of girls in schools is less compared to boys because girls are made to work and stay sticked to home, Mostly Girls are discriminated in all ways.
Some girls die in the womb, Some girls life's are spoiled without education . So, Girls strength is less .
We need to educate everyone that One daughter isn't a TENSION but equal to Ten SONS.
Women empowerment , Awareness regarding education , Strict laws if discriminated / harassed should be done.
GOVT of India, has launched several moments like " Beti bachao, Beti padhao " , Also they restricted gender determination when the baby is in mother's womb.

Let no. Of boys be 7x and no of girls be 5x.
1)given no. Of girls = 50
=>5x=50
x=50/5=10
Therefore,x=10
No.of boys = 7x = 7 X 10= 70
Total no. Of students = 70 + 50 = 120
The strength of the girls is less than the boys mostly because in some of the rural areas .. Still female education is not considered important
