Direction : Study the following question carefully and choose the right answer.
1. If in a certain language, 'oka peru', means 'fine cloth', 'meta lisa' means 'clear water' and 'dona lisa peru' means 'fine clear weather', which word in that language means 'weather'?
A. peru
B. oka
C. meta
D. dona
E. None of these 
Answer: Option D
Explanation:
Statement 1: fine cloth                                
Code Statement 1: oka peru
Statement 2: clear water                             
Code Statement 2: meta lisa
Statement 3: fine clear weather                  
Code Statement 3: dona lisa peru
                    
In the [latex]1^{st}[/latex] and [latex]3^{rd}[/latex] statements, the common code-word is 'peru' and the common word is 'fine'. So, 'peru' means 'fine'.
In the [latex]2^{nd}[/latex] and [latex]3^{rd}[/latex] statements, the common code-word is 'lisa' and the common word is 'clear'. So, 'lisa' means 'clear'.
Thus, in the [latex]3^{rd}[/latex] statement, 'lisa' means 'clear' and 'peru' means 'fine'. So, 'dona' means 'weather'.
2. In a certain code language, ‘mink yang pe’ means ‘fruits are ripe’, ‘pe lao may mink’ means ‘oranges are not ripe’ and ‘may pe nue mink’ means ‘mangoes are not ripe’. Which word in that language means ‘manoges’?
A. may
B. pe
C. nue
D. mink
E. None of these 
Answer: Option C
Explanation:
Statement 1: fruits are ripe                                
Code Statement 1: mink yang pe
Statement 2: oranges are not ripe                    
Code Statement 2: pe lao may mink
Statement 3: mangoes are not ripe                    
Code Statement 3: may pe nue mink
The words except 'mangoes' in the [latex]3^{rd}[/latex] statement are being repeated in the [latex]2^{nd}[/latex] statement. By removing the code-words which are getting repeated; 'may', 'pe' and 'mink', we are left with the code-word 'nue' which stands for the word 'mangoes'
3. In a certain code language, ‘sun shines brightly’ is written as ‘ba lo sul’, ‘houses are brightly lit’ as ‘kado ula ari ba’ and ‘light comes from sun’ as ‘dopi kup lo nro’. What code-words are written for ‘sun’ and ‘brightly’ respectively?
A. ba, sul
B. sul, lo
C. lo, ba
D. ba, l 
Answer: Option C
Explanation:
Statement 1: sun shines brightly                      
Code Statement 1: ba lo sul
Statement 2: houses are brightly lit                  
Code Statement 2: kado ula ari ba
Statement 3: light comes from sun                   
Code Statement 3: dopi kup lo nro
In the [latex]1^{st}[/latex] and [latex]3^{rd}[/latex] statements, the common word is 'sun' and the common code-word is 'lo'. So, 'lo' is the code for 'sun'.
In the [latex]1^{st}[/latex] and [latex]2^{nd}[/latex] statements, the common word is 'brightly' and the common code-word is 'ba'. So, 'ba' is the code for 'brightly'.
4. In a certain code language, ‘si po re’ means ‘book is thick’, ‘ti na re’ means ‘bag is heavy’, ‘ka si’ means ‘interesting book’ and ‘de ti’ means ‘that bag’. What should stand for ‘that is interesting’ in that code language?
A. ka de re
B. ti po ka
C. ka re na
D. de si re
E. None of these 
Answer: Option A
Explanation:
Statement 1: book is thick                       
Code Statement 1: si po re
Statement 2: bag is heavy                       
Code Statement 2: ti na re
Statement 3: interesting book                 
Code Statement 3: ka si
Statement 4: that bag                            
Code Statement 4: de ti
In the [latex]1^{st}[/latex] and [latex]2^{nd}[/latex] statements, the common word is 'is' and the common code-word is 're'. So, the code-word for 'is' is 're'.
In the [latex]1^{st}[/latex] and [latex]3^{rd}[/latex] statements, the common word is 'book' and the common code-word is 'si'. Thus, the other code-word in the [latex]3^{rd}[/latex] code statement; 'ka' means 'interesting'.
In the [latex]2^{nd}[/latex] and [latex]4^{th}[/latex] statements, the common word is 'bag' and the common code-word is 'ti'. So, 'ti' means 'bag'. Thus, the other code-word in the [latex]4^{th}[/latex] code statement; 'de' means 'that'.
Thus, the codes for 'that', 'is' and 'interesting' are 'de', 're' and 'ka' respectively. So, any combination of these three codes will be the required code.
5. In a certain code language, ‘col tip mot’ means ‘singing is appreciable’, ‘mot baj min’ means ‘dancing is good’ and ‘tip nop baj’ means ‘singing and dancing’, which of the following means ‘good’ in that code language?
A. not
B. min
C. baj
D. Can't be determined
E. None of these 
Answer: Option B
Explanation:
Statement 1: singing is appreciable             
Code Statement 1: col tip mot
Statement 2: dancing is good                       
Code Statement 2: mot baj min
Statement 3: singing and dancing                
Code Statement 3: tip nop baj
We have to find the code-word for the word 'good' which is coming only for once in [latex]2^{nd}[/latex] statement. The other two words 'dancing' and 'is' are getting repeated once each in [latex]3^{rd}[/latex] and [latex]1^{st}[/latex] statements respectively.
By removing the repeated code-words; 'mot' and 'baj' from the [latex]2^{nd}[/latex] statement, no matter which word each stands for, we are left with only the code-word 'min' that evidently stands for the word 'good'.
