In a certain code language, ‘SOIL’ is coded as ‘1547’ and ‘COIL’ is coded as ‘7124’. What is the code for ‘C’ in the given code language?
2
List the letters and digits for each word. SOIL uses the digits {1, 5, 4, 7} and COIL uses the digits {7, 1, 2, 4}.
The two words share three letters: O, I and L. So the digit for C in COIL must be the one digit that does NOT belong to these shared letters.
Take the intersection of the two digit sets: {1, 5, 4, 7} and {7, 1, 2, 4} give the common digits {1, 4, 7}, which belong to the common letters O, I and L.
In SOIL the leftover digit 5 is therefore S, and in COIL the leftover digit 2 is therefore C.
Hence, the answer is 2.
