Question

There are $650$ students in a school. If the number of girls is $106$ more than the boys, how many boys are there in the school?

• A. $250$
• B. $272$
• C. $324$
• D. $378$

Answer 1

The correct option is B $272$

Let the number of boys $=x$

Number of girls is $106$ more than the boys.

So, the number of girls $=x+106$

Now the total number of students $=$ number of boys $+$ number of girls

$=x+x+106$

$=2x+106$

Now,

$2x+106=650$

$2x=650-106$

$2x=544$

$x=\frac{544}{2}=272$
