Question

Find the value $x$ from the given table :
$$\begin{array}{ccccccccc}X& 100& 250& 200& 50& 125& 1000& 4& 40\\ Y& 20& 8& 10& 40& x& 2& 500& 50\end{array}$$

• A. 16

Answer 1

The correct option is A 16
We see that the quantities X and Y are inversely proportional, as the corresponding values of X and Y are such that
XY = constant.
Therefore,
$100\times 20=$ $125\times x$
$\therefore x=16$
