N P M A N

Now, if 'P' stands for 6, 'M' for 4 and 'Q' for 5, then what is the difference between the square of Q and A ?

• A. 36
• B. 12
• C. 24
• D. 48

Answer 1

The correct option is C 24

P=6,M=4 and Q=5.
4 N 6
x 6 N
S 5 N
+N 5 5 6 x
N 6 4 A N
Where A=5+6=11 so A=1 & carry over 1+S+5=14, So S=8
Therefore,
4 N 6
x 6 N
8 5 N
+N 5 5 6 x
N 6 4 A N
Q*Q-A*A=251=24.
