  1. Circle

    1. Angle subtended by an arc at centre is 120°. Angle at any point on the major arc:

    • A. 30°
    • B. 40°
    • C. 50°
    • D. 60° (Correct)

    Explanation: Angle at major arc=120°/2=60°.

  2. Similar Triangles

    2. In similar triangles, perimeters are 12 and 20. If smallest side of smaller triangle is 3, smallest side of larger is:

    • A. 4
    • B. 5 (Correct)
    • C. 6
    • D. 7

    Explanation: Ratio=12:20=3:5. Smallest side of larger=3×20/12=5.

  3. Cone

    3. Slant height of cone with r=5 and h=12 is:

    • A. 11 cm
    • B. 12 cm
    • C. 13 cm (Correct)
    • D. 14 cm

    Explanation: l=√(r²+h²)=√(25+144)=13 cm.

  4. Triangle

    4. Pythagoras theorem applies to:

    • A. All triangles
    • B. Acute triangles
    • C. Right triangles (Correct)
    • D. Obtuse triangles

    Explanation: Pythagorean relation holds only for right-angled triangles.

  5. Quadrilateral

    5. Diagonals of a rhombus are 24 cm and 10 cm. Side of rhombus:

    • A. 11 cm
    • B. 12 cm
    • C. 13 cm (Correct)
    • D. 14 cm

    Explanation: Side=√(12²+5²)=√169=13 cm.

  6. Angles

    6. In a cyclic quadrilateral, opposite angles sum to:

    • A. 90°
    • B. 120°
    • C. 180° (Correct)
    • D. 360°

    Explanation: Opposite angles of a cyclic quadrilateral are supplementary.

  7. Hemisphere

    7. Curved surface area of hemisphere of radius 14 cm:

    • A. 1144 cm²
    • B. 1232 cm² (Correct)
    • C. 1344 cm²
    • D. 1432 cm²

    Explanation: CSA=2πr²=2×22/7×196=1232 cm².

  8. Tangent

    8. Two tangents from external point make angle 60° between them. Angle subtended at centre by chord joining tangent points:

    • A. 100°
    • B. 110°
    • C. 120° (Correct)
    • D. 130°

    Explanation: Angle at centre = 180°−60°=120°.
