Question

Five children were administered psychological tests to know their intellectual levels. In the report, psychologists pointed out that the child A is less intelligent than the child B, the child C is less intelligent than the child D, the child is less intelligent than the child C and child A is more intelligent than the child E. Which child is the most intelligent ?

• A. A
• B. B
• C. D
• D. E

Answer 1

The Correct Option is C

To determine the most intelligent child based on the provided information, let's summarize the relationships between the children:

\(A\) is less intelligent than \(B (A < B)\).
\(C\) is less intelligent than \(D (C < D)\).
\(A\) is less intelligent than \(C (A < C)\).
\(A\) is more intelligent than \(E (A > E)\).

Now let's combine this information:

\(A < B\)
\(A < C < D\) (since \(C\) is less intelligent than \(D\), and \(A\) is less intelligent than \(C\))
\(A > E\)

Therefore, the hierarchy of intelligence from least to most intelligent is:
\(E < A < C < D\).
Since \(B\) is more intelligent than \(A\), but there is no direct comparison between \(B\) and \(D\), we know the hierarchy of \(A, C,\) and \(D\) but not between \(B\) and \(D\).

From the given information, \(D\) is the most intelligent child.

So, the correct option is \((C): D\).
