Question

The number of boys in a class is 11 more than the number of girls in the class. If there are 75 students in the class, find the number of boys and girls in the class

Answer 1

No. of boys= 11 more than no. of girls
No. girls= ?
No. of boys= ?
total students in class= 75
hence, 75 - 11 = 64

$\frac{64}{2} = 32$
no of boys=
$32 + 11 = 43$

Answer 2

Given,

The number of boys in a class is 11 more than the number of girls in the class and there are 75 students in the class.

To Find,

The number of boys and girls in the class.

Solution,

Let the number of girl in class = x

Now,

According to the question, we have,

The number of boys = 11+x

Also given,

Total number of students = 75

So,

11+x+x = 75

After solving the above, we get

$11 + x + x = 75$

$11 + 2x = 64$

$x = 32$

The number of girl = 32,

On putting the value of x, we get

Number of boys = 11+x = 11 + 32

= 43

Henceforth, the number of boys and girl are 43 and 32 respectively.
