Let the unknown number whose value we have to find be x. This means that we have to find the value of x. We can do this with the given information. It is said that the student divided the number ‘x’ by 2 and got an answer of 2. This means that $\dfrac{x}{2}=2$.From the above equation we can write that $x=2\times 2=4$. Therefore, the number that is being multiplied or divided by 2 is 4. It is said that the boy had to multiply 4 by 2. We know that when we multiply 4 by 2, we get an answer of 8.Therefore, the correct answer is 8.
Note:Be careful while the linear equation in x. Students may accidently write the equation as $\dfrac{2}{x}=2$It is given that when we divide the number ‘x’ by 2, we get an answer of 2 and not 2 divided by the number ‘x’ results 2.
