    Solution :

    The word is divided into three equal sections, and the letters of first and third sections are written backwards. Similarly, In the first and second statements, the common code digit is '4' and the common word is 'is. So, '4' is the code for 'is'. In the second and third statements, the common code digit is '6' and the common word is 'sea'. So, '6' is the code for 'sea'. Thus, in the second statement, '2' is the code for 'deep'. In the first and third statements, the common code digit is' 8' and the common word is 'blue'. So, '8' is the code for 'blue'. Thus, in the first statement, '1' is the code for 'sky'.
