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 greater than 5, then 'N' stands for:

• A. $6$
• B. $7$
• C. $8$
• D. $6or7$

Answer 1

The correct option is D $6or7$

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 If N > 5, then N can either be 6 or 7 or 8, but Z=8 So, N = 6 or 7. Hence option (4).
