Ask any numismatist and he or she is sure to tell you that rare coins are invaluable. So, RARE + COIN should have been equal to INVALUABLE. However, my friend has given me this problem to solve, according to which RARE + COIN = TEPID. Now, whatever does that mean?
Anyway, this has nothing to do with linguistic skills but is an alphametic poser. Each alphabet stands for a unique number from 0 to 9. The sum works out to be true when the alphabets are replaced by their corresponding numbers. The four-digit numbers, whose sum has to be found, cannot start with zero. Thus, "R", "C" and "T" cannot be zero.
To start with, I will tell you what "A" stands for. A = 6. Now you have to find the other numbers so that the sum is true.
Here is the alphametic once again:
