The Correct Option is A

Solution and Explanation

The lightest article is C because:

\(A = 9C\)  
\(B = 4.5C\)  
\(D = 2C\)  
\(E = 4C\)

Since \(w_A > w_E > w_C\), article C is the lightest.

The correct option is (A): C

The Correct Option is C

Solution and Explanation

From the given conditions:

\(w_A = 9w_C\)
\(w_B = 4.5w_C\)
\(w_D = 2w_C\)
\(w_E = 4w_C\)

Since \(w_A > w_E > w_C\), article E is lighter than A and B.

The correct option is (C): A,B

The Correct Option is B

Solution and Explanation

From the weight relationships:

\(w_E = 4w_C\)
\(w_D = 2w_C\)
\(w_C\) is the lightest.

Since \(w_E = 4w_C\), it is clear that:

\(w_E > w_D\) (because \(4w_C > 2w_C\))
\(w_E > w_C\) (because \(4w_C > w_C\))

Thus, article E is heavier than both C and D.

The Correct Option is C

Solution and Explanation

From the weight relationships:

\(w_A = 9w_C\)
\(w_B = 4.5w_C\)
\(w_E = 4w_C\)
\(w_D = 2w_C\)
\(w_C\) is the base weight.

Since \(w_A = 9w_C\), article A is the heaviest in weight.
