Question

In the given question, select the related number from the given alternatives.
$235$ $:$ $587$ $:$ $:$ $435$ $:$ $?$

• A. $788$
• B. $989$
• C. $789$
• D. $988$

Answer 1

The correct option is C $789$

In $235$, $2+3=5$, $3+5=8$ and $2+5=7$ $\Rightarrow (235\to 587)$

Similarly, in $435$, we get:

$4+3=7$

$3+5=8$

$4+5=9$

$\Rightarrow (435\to 789)$

So, $235:587::435:789$

$\therefore$ The correct answer is $789$. $\left[C\right]$
