Friends, here are the Solutions with explanations for my previous lesson, Data Sufficiency Practice Problems (Lesson 2). You can read that lesson from here before checking these answers. 
  1. The colour of fresh grass is 'green' and as given is 2, 'green' is called 'brown'. So, the colour of fresh grass is 'brown'. 
  2. In 1 and 2, the common codes are 'nip' and 'sre' and the common words are 'is' and 'beautiful'. So, 'nip' cannot be found out. 
  3. In the given statement and 1, the common word is 'they' and the common code word is 'nop'. So, 'nop' is the code for 'they'. In the given statement and 2, the common word is 'like' and the common code word is 'al'. So, 'al' is the code for 'like'. Thus, in the given statement, 'ed' is the code for 'flowers'. 
  4. The only word common to 1 and 2 is 'clear' and as such, only the code for 'clear' can be ascertained from the given information. 
  5. From the two statements given in 1, the code for the only common word 'beautiful' can be determined. From the two statements given in 2, the code for the only common word 'red' can be determined. In 1 and 2, the common words are 'rose' and 'flower' and the common code words are 'de' and 'la'. So, the code for 'flower' is either 'de' or 'la'. 
  6. In the given statement and 1, the common word is 'good' and the common code word is 'co'. So, 'co' is the code for 'good'. In the given statement and 2, the common words are 'He' and 'is' and the common code words are 'sin' and 'bye'. So 'sin' and 'bye' are the codes for 'He' and 'is'. Thus, in the given statement,'co' is the code for 'good'. 
  7. In 1 and 2, the common word is 'is' and the common code word is 'ke'. So 'ke' is the code for 'is'. 
  8. In the two statements given in 1, the common words are 'But', 'None', 'And' and the common code words are 'Ne', 'Pa', 'Lo'. So, 'Ne', 'Pa' and 'Lo' are codes for 'But', 'None' and 'And'. Thus, in the first statement, 'Sic' is the code for 'No.
  9.  
    1. In 'right of wrong' and 'he is right', the common word is 'right' and the common code word is 'nik'. So 'nik' means 'right'. In 'right or wrong' and 'that is wrong', the common word is 'wrong' and the common code word is 'te'. So, 'te' means 'wrong'. Thus, in 'right or wrong', 'sa' is the code for 'or'. 
    2. In 'that right man' and 'this or that', the common word is 'that' and the common code word is 'pa'. So, 'pa' means 'that'. In 'this or that' and 'tell this there', the common word is 'this' and the common code word is 'ne'. So, 'ne' means 'this'. Thus, in 'this or that', 'sa' is the code for 'or'. 
  10. In 'You eat many mangoes' and 'Who others eat bananas', the common word is 'eat' and the common code word is 'Le'. So, 'Le' means 'eat'. In 'You eat many mangoes' and 'They eat bananas and mangoes', the common code word 'Le' stands for 'eat'. So, the other common code word 'Na' stands for the other common word i.e., 'mangoes'.
