In a certain code language 'I' is coded as '18' and 'R'

Solution

The logic followed here is: The two of the place value of the given letter is the code of that letter. The place value of 'I' is '5', so, 'I' is coded as 2 X 9 = '18'. The place value of 'R' is '18', so, 'R' is coded as 2 X 18 = '36'. Similarly, The place value of 'T' is '20', so, 'T' is coded as 2 X 20 = '40' The place value of 'I' is '9', so, 'I' is coded as 2 X 9 = '18'. The place value of 'N' is '14', so, 'N' is coded as 2 X 14 = '28'. So, 'TIN' will be coded as '40, 18, 28'.
