Decipher the following multiplication table:
M A D
B E
-------------
M A D
R A E
-------------
A M I D
Correct answer: D
Explanation
It is clear that E = 1 as MAD×E=MAD
From the hundred's line, M + A = 10 + M or 1 + M + A = 10 + M
As A = 10 not possible, A = 9
So I = 0.
and From the thousand's line R + 1 = A. So R = 8.
M 9 D
B 1
-------------
M 9 D
8 9 1
-------------
9 M 0 D
-------------
As B×D = 1, B and D takes 3, 7 in some order.
If B = 7 and D = 3, then M93×7 = _51 is not satisfied. So B = 3 and D = 7.
2 9 7
3 1
-------------
2 9 7
8 9 1

9 2 0 7
