Question

What is the angle subtended by the sector at the centre of a circle? Statement (I): Perimeter of the sector is 16 units.
Statement (II): Arc length of that sector is 10 units.

• A. Statement (I) alone is sufficient.
• B. Statement (II) alone is sufficient.
• C. Both statements (I) and (II) are sufficient.
• D. Neither statement is sufficient.

Hint:

For sector problems, the angle cannot be determined unless enough information is available to calculate both the radius and the arc length. One equation with two unknowns is usually insufficient.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This item evaluates fundamental computer vocabulary by requesting the expansion of the acronym "GUI".


Step 2: Detailed Explanation:
In the realm of computing, GUI is the abbreviation for Graphical User Interface.
