Question

In the given question, select the related number from the given alternatives.
$9$ $:$ $50$ $:$ $:$ $?$

• A. $22$ $:$ $110$
• B. $18$ $:$ $190$
• C. $15$ $:$ $225$
• D. $20$ $:$ $105$

Answer 1

The correct option is D $20$ $:$ $105$

In the first pair of numbers i.e. $9:50$

$(9\times 5)+5=50$

So, we need to find the pair of numbers which follow the same relation as $9$ and $50$ follows.

From the given options,

$(20\times 5)+5=105$

So, $9$ and $50$ are related the same way $20$ and $105$ are related.

$\therefore$ The correct answer is $\left[D\right]$.
