Question

Given

B A N A

+ N A N A

---------------------

V L W L

Where A = 1 and N = 3.

What will be the value of B, if V is a prime number?

• A. $6$
• B. $4$
• C. $5$
• D. $7$

Answer 1

The correct option is B $4$

It is given that $A$ $=1$ and $N$ $=3$

Therefore,

$L=A+A=2$

$W=N+N=3+3=6$

$B+N=V$

$\Rightarrow B+3=V$

If $V$ is a prime number then it can be one among $\{3,5,7,11\}$

For $V=3,B=0$

For $V=5,B=2$

For $V=7,B=4$

For $V=11,B=8$

Only option B satisfies the condition.

Hence, option B.
