Question

On his birthday, Manoj planned that this time he celebrates his birthday in a small orphanage Centre. He bought apples to give to children and adults working there. Manoj donated 2 apples to each children and 3 apples to each adult working there along with Birthday cake. He distributed total 60 apples. So from the given data the linear equation so formed is 2x + 3y = 60.


If the number of children is 15, then the number of adults is

Answer 1

Let the number of children be X and that of each adult be y.

number of children = 15 (given)

number of adults = ?

Now,

since 2x + 3y = 60

so 2*15 + 3y = 60 ( X = number of children)

30 + 3y = 60

3y = 60 - 30

3y = 30

y= 30/3

y = 10

So, the number of adults is 10.
