Question

Frame an equation for the following statement:
A number is four times another number and their difference is $12$.

• A. x + 4x=12
• B. 4x - x = 12
• C. 4x = 12
• D. Either A or B

Answer 1

Answer: (A), (B)

The correct options are
A

x + 4x=12

B

4x - x = 12

Let the number be $x$.
The other number is four times x, i.e. $4x$.
Difference between them is,
$4x-x=3x$
$\text{Therefore, 4x - x = 12 is the equation.}$
