Common Information
Answer the questions on the basis of the information given below.
In a school, there are four chemical laboratories namely Lab 1, Lab 2, Lab 3 and Lab 4. There are only six types of acids that are available in these laboratories. The following table provides information about the number of bottles of each type of acid in each of these laboratories.
Every bottle of acid in the chemical laboratories is further categorized on the basis of its capacity under one or the other of the five different categories namely ‘S’, ‘M’, ‘L’, ‘XL’ and ‘XXL’.
The following chart provides information about the number of bottles of acids in each of the mentioned categories (on the basis of its capacity) as a percentage of the total number of bottles of acids in these laboratories.
Q1. 
Common Information Question: 1/5 Additional Information for questions 1 and 2: In Lab 2 as well as Lab 3, the number of bottles of acids in the category XL as a percentage of the total number of bottles of acids in the respective laboratories is not more than 1%. In Lab 1, the total number of bottles of acids in the category XL as a percentage of the total number of bottles of acids in Lab 1 cannot be less than 
A.  2% 

B.  3% 

C.  4% 

D.  5% 

E.  6% 
Q2. 
Common Information Question: 2/5 Additional Information for questions 1 and 2: In Lab 2 as well as Lab 3, the number of bottles of acids in the category XL as a percentage of the total number of bottles of acids in the respective laboratories is not more than 1%. If the ratio of the number of bottles of acids in Lab 1 and Lab 4 that are in the category XL is 2: 7, then what can be the difference between the number of number of bottles of acids in Lab 1 and Lab 4 that are not in the category XL? 
A.  212 

B.  202 

C.  207 

D.  Either (A) or (C) 

E.  Either (A) or (B) 
Q3. 
Common Information Question: 3/5
All the bottles containing one or the other of the three acids namely Sulphuric, Nitric and Nitrous are in one or the other of the three categories S, M and L only. Also, the total number of bottles of Benzoic, Hydrochloric and Salicylic acid that are in one or the other of three categories S, M and L are ‘a’, ‘b’ and ‘c’ respectively. Which of the following can be equal to the ratio $a : b : c$? 
A.  2 : 31 : 5 

B.  13 : 17 : 17 

C.  15 : 7 : 19 

D.  13 : 7 : 30 

E.  None of these 
Q4. 
Common Information Question: 4/5 Additional Information for questions 3 and 4: All the bottles containing one or the other of the three acids namely Sulphuric, Nitric and Nitrous are in one or the other of the three categories S, M and L only. Also, the total number of bottles of Benzoic, Hydrochloric and Salicylic acid that are in one or the other of three categories S, M and L are ‘a’, ‘b’ and ‘c’ respectively. If the value of $a$ is maximum possible, then the number of bottles of Benzoic acid in Lab 2 that do not belong to any of the three categories S, M and L cannot be less than: 
A.  76 

B.  75 

C.  78 

D.  77 

E.  79
