If 'PARK' is coded as '1729' and 'DEAF' is coded as

Solution

The sum of the place value of the first two letters is the first two digits of the code, the sum of the place value of the next two letters are the next two digits of the code. For PARK, Sum of the place value of 'P' and 'A' = 16 + 1 = 17 ; Sum of the place value of 'R' and 'K' = 18 + 11 = 29 For DEAF, Sum of the place value of 'D' and 'E' = 4 + 5 = 09; Sum of the place value of 'A' and 'F' = 1 + 6 = 07 For MELT, Sum of the place value of 'M' and 'E' = 13 + 5 = 18; Sum of the place value of 'L' and 'T' = 12 + 20 = 32
