Answer 1

As per given by the question,

There are given that ,

The total number of student is 47.

Now,

The number of male is 11 more than numbers of females.

So,

Suppose, the number of students is x.

Then,

The female is x, then

The number of males is,

`11+x`

Beacuse 11 more than females.

Then,

According to the question,

There are total student is 47.

Now,

`\begin{gathered} x+11+x=47 \\ 11+2x=47 \\ 2x=47-11 \\ 2x=36 \end{gathered}`

Then,

`\begin{gathered} 2x=36 \\ x=(36)/(2) \\ x=18 \end{gathered}`

The numbers of female student is 18.

Then,

The numbers of male student is,

`\begin{gathered} x+11=18+11 \\ =29 \end{gathered}`

Hence, the number of males student is 29 and the numbers of female student is 18.
