Question

$$\begin{array}{ccccc}X& 2& 4& 5& 50\\ Y& 4& 8& x& 100\end{array}$$

What is the constant that is used to find the missing values of the table?

• A. 1/2
• B. 3/4
• C. 4/3
• D. 5/2

Answer 1

The correct option is A

1/2

The constant, also known as the constant of proportionality, is given by finding the ratio $\frac{X}{Y}$. The corresponding values of X and Y will have a constant value for $\frac{X}{Y}$. Now, if we take X = 2 and Y = 4, we get the constant of proportionality as $\frac{1}{2}$.
