|The given explanation is more complicated one, just be logical.
As the ratio is 3:2.
First divide 60 as 30 boys and 30 girls.
Then apply the conditions, you will get the answer quickly.

|The above explanation is not correct as the correction will be done in 5th and 6th line were,
Let the no.of boys not participating in sports be (35-y) ,
Then, the no.of girls not participating in sports is (y+5).
After this correction is done then there will be no confusion.

|Can we divide 60 students into the ratio of 3:2 and them we solv ethe question accordingly??
Is it possible??

|Why is the girl is equal to 10?|
|Upasana said: (Oct 16, 2015)|
|@ Saravanan : The ratio is given to be 3:2, hence we cannot divide it equally into 30 boys and 30 girls.
@ Abhishek : No, we can't. It is given that 60 is the TOTAL number of students and 3:2 is the ratio of the students PARTICIPATING.

|No. Of boys and girls participating in sports is 3:2. Boys participating in sport is 15 so, girls are 10. Total 25.
Remaining are non-sport. i.e . 35. In that question no. of girls participating in sports 5 more than no. of boys so. Boys 15. And girls 20.

|How can 3x+2x be equated to 15?
It must be equated to the total number of students participating.
|Greeshma said: (Nov 7, 2020)|
|Total no of students =60.
Participating boys and girls are in the ratio of = 3 : 2 = 3x:2x.
According to question, participating boys are 15 members so,by this we can say
3x = 15.
Where x=5 ---->(1)
We got x value then 2x=10----->(2).
In question they given the non participating girls 5 more than boys so let's assume the boys who are not participating as y---> (3) than the girls who are not participating as y+5--> (4)
Then total will come when we add participating boys+participating girls +non participating boys +non participating girls;
So we (1)+(2)+(3)+(4) = 60
15+10+y+y+5 = 60
30+2y = 60
2y = 60-30
2y = 30
Y = 30/2
Y = 15 we got non participating girls so to get total girls, participating girls +non participating girls.
15 + 15 = 30.
