Worked Examples

Example-1

What is the code of ‘is’ in the code language?

  1. In the code language, ‘sa ka pa’ means ‘Paper is white’.
  2. In the same code language, ‘nak pa tak’ means ‘He is smart’.

Solution

Statement I alone or statement II alone is not sufficient to answer the question as the order of the code need not be the same as that of the order of words.

 

We observe that ‘is’ is the common word in the statements ‘Paper is white’ and ‘He is smart’. So, the common code in their codes (in this case ‘pa’) should be the code of ‘is’.

 

Answer: Data given in both the statements I and II are necessary to answer the question.
 

 

Example-2

Five people A, B, C, D and E are sitting in a row. Who is sitting to the immediate right of A?

  1. C is third to the left of B and A is second to the right of C.
  2. B is to the immediate left of E who is second to the right of A.

Solution

Statement I gives information regarding the position of A, B and C. On plotting this information, the seating diagram appears as under:

 

C - AB

 

So, we can answer who is sitting to the immediate right of A.

 

According to the information given in statement II, the seating diagram takes the following form.

 

A B E

 

Now also, we can answer who is sitting to the immediate right of A.

 

Answer: The data either in statement I alone or in statement II alone are sufficient to answer the question.
 

 

Example-3

Among A, B, C, D and E who is heaviest?

  1. A and D are heavier than B and E but none of them is the heaviest.
  2. A is heavier than D but lighter than C.

Solution

From statement I, it is clear that none of A and D is the heaviest, though they are heavier than B and E. This implies that C is the heaviest.

 

Statement II implies that C is heavier than both D and A.

 

But the position of B and E is not indicated in this statement. Hence, we cannot answer the question.

 

Answer: Data in statement I alone are sufficient to answer the question, but the data in statement II alone are not sufficient to answer the question.
 

 

Example-4

Raju’s and Kumar’s salaries are in the ratio 5:3. What is Raju’s salary?

  1. Kumar’s salary is 60% of Raju’s salary.
  2. Kumar’s salary is 18,000 P.M.

Solution

Statement I is the other form of the information given in the question. It does not provide any other data to find Raju’s salary.

 

Statement II gives the salary of Kumar (18,000 P.M). So, Raju’s salary will be

Answer: The data given in statement II alone are sufficient to answer the question, but the data in statement I alone is not sufficient to answer the question.
 

 

Example-5

How many people visited the exhibition on Sunday?

  1. Each entry pass holder can take up to 3 persons with him/her.
  2. Among all, 356 passes were sold on Sunday.

Solution

From statements I and II, we can find the maximum number of visitors who could visit the exhibition on Sunday. We cannot find the exact number of visitor, as we do not know how many people each pass holder took with him.

 

Answer: The data given in both the statements I and II together are not sufficient to answer the question.
