Instructions

Read the following scenario and answer the TWO questions that follow.

41 applicants have been shortlisted for interviews for some data analyst positions. Some of the applicants have advanced expertise in one or more fields among the following: data analysis, database handling and coding. The numbers of applicants with different advanced expertise are given in the 2 × 8 table below.
The number of applicants with advanced expertise in all three fields is given as x in the table, where x is a non-negative integer.

Question 18

What BEST can be concluded about the value of x?

Solution

Here, we need to represent all the given data in a three sets venn-diagram that is Data Analytics (A), Database Handling (H), and Coding (C).

If we write all the data that is given in the table, we will get the following diagram:

Now we need to infer the characteristics of x, which can be concluded from the given information.

We know that $$2-x\ge\ 0$$, hence the possible values of x is 0, 1, 2

It is also known that $$x-2\ge\ 0$$, which implies the possible values of x is 2, 3, 4, ....

Now, from both equation, the only common value of x is 2.

Hence, x can take only 2 as the value.

The correct option is B
