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.
$MNOP$
$\underset{–}{+AQRP}$
$\underset{–}{ZZZZ}$
If $M>N$ and the value of $N=6$, then what is the value of R?

• A. $2$
• B. $1$
• C. $3$
• D. Cannot be determined

Answer 1

Answer: (D)

Cannot be determined

For simplicity, let us replace all the Ps with 4 as $P=4$ (given).
$MNO4$
$\underset{–}{AQR4}$
$\underset{–}{ZZZZ}$
As $4+4=Z$ that means $Z=4+4=8$. Now, replacing all Zs by 8.
$MNO4$
$\underset{–}{AQRS}$
$\underset{–}{8888}$
When N= 6 and M > N, then M= 7. But since the value of R has no relation with the values of either M or N, therefore, the value of R cannot be determined with the given information.
