Direction: The following question is accompanied by three statements ...
⇒ Statement I alone is not sufficient to answer the question.
From statement II,
Area of the square = 144 cm2
⇒ Side of the square = 12 cm
Perimeter of the square = 12 × 4 = 48 cm
⇒ Height of the cylinder = 2 × 48 = 96 cm
Statement II alone is not sufficient to answer the question.
From statement III,
Diameter of the cone = 3 × breadth of the rectangle
Perimeter of the rectangle = 2 × (l + b) = 84 cm
∵ Breadth cannot be determined,
⇒ Statement III alone is not sufficient to answer the question.
If we combine all the statements, we can determine the height of the cone but not the radius or the slant height.
∴ None statement is sufficient to answer.
Hence, the correct option is (E).
