Question

In the following addition each of the letters denote a different integer. Each letter stands for the same integer throughout where 'P' stands for 4.

M N O P

+A Q R P

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

Z Z Z Z

If the value of N is 6 and M > N, then what is the value of A?

• A. 2
• B. 1
• C. 3
• D. None of these

Answer 1

The correct option is B 1

For simplicity, let us replace all the Ps with 4 as P=4 (given).
M N O 4
+A Q R 4
Z Z Z Z
As $4+4=$Z that means Z = $4$$+4=8$
Now, replacing all Zs by 8.
M N O 4
+A Q R 4
8 8 8 8
As(M > N), M= 7
Therefore, $A=8-7$ (M)$=1$

So, option B.
