Question

A 540 m-long rectangular plot is to be fenced. Find the cost of fencing per square metre.
I. Breadth of the plot is $60$ m.
II. Length of the plot is $120$ m.

• A. I alone sufficient; II alone not.
• B. II alone sufficient; I alone not.
• C. Either I alone or II alone sufficient.
• D. Even I + II together not sufficient.
• E. I + II together necessary.

Hint:

Check that the question's target quantity is actually computable from the variables given. Missing unit rates often make data insufficient even when dimensions are known.

Answer 1

The Correct Option is D

1. Statement I (breadth = 60 m): Combined with the stem's perimeter information, the length can be deduced, giving the full area, but no cost rate.
2. Statement II (length = 120 m): Similarly gives the missing dimension and area, but again no cost rate.

No statement, alone or combined, ever supplies a rupee rate per square metre, so the cost of fencing per square metre cannot be found from any combination of the given data.
