xxTIMURxx [149]

Answer:

Therefore there total of 39 children presented in group of people who attended a ball game.

Step-by-step explanation:

Given:

Total people present=52 .

And there are 3 times children as adults

To Find:

No.of Children Present in Group.

Solution:

<em>Consider  'x'  be the children and 'y' be Adults presented in group.</em>

<em />

So there are total of 52 people.

Therefore Equation becomes,

x+y=52.

And also there  are 3 times children presented in group as adults were.

So

Children=3 times adults

i.e.x=3y

Using in above Equation we get ,

x+y=52

3y+y=52

4y=52

y=52/4

y=13

Hence there are 13 adults  presented in group

So ,

No.of Children=x=3y

=3(13)

=39

No.of.Children =39
