Question

There are 750 students in a school. If the number of girls is 110 more than boys and if there are "x" boys, then the linear equation is:

• A. $x+x+110=750$
• B. $2x+110=750$
• C. $x+x=750+110$
• D. $110x=750$

Answer 1

Answer: (A), (B)

The correct options are
A

$x+x+110=750$

B

$2x+110=750$

If "x" is the number of boys, then x+ 110 is the number of girls.

Total number of students = number of boys + number of girls
$\Rightarrow$ $750=x+x+110$

On interchanging LHS and RHS,
$\Rightarrow$$x+x+110=750$
$\Rightarrow$$2x+110=750$
