Illustration: In the following question on multiplication, each letter always stands for the same digit.
For which digit does "D" stand ?
A. 3 B. 8 C. 9 D. 7
Answer : A
Solution : - P = 0, because S + 0 = S
M + M = P, which implies M = 5, because P = 0
A A = M = 5, so, A = 2, because 1 is carry.
D D = S, which is 1 digit number, D cannot be 1 or 2. Hence, D = 3
