Question

In the following question, two pairs of similarly related numbers are given. Select the related number from the given alternatives and complete the second pair.

$3:11::7:?$

• A. $34$
• B. $39$
• C. $46$
• D. $51$

Answer 1

The correct option is D $51$

$3^2+2=11$
So, if the first number is $x$. Then second number is $x^2+2$.
Thus, the relationship is $x,x^2+2$.

So, second number will be $7^2+2=49+2=51$
