4What is 15% of 200?
Answer: C — 30
15% of 200 = (15/100) × 200 = 15 × 2 = 30. Percentages are calculated by multiplying the percentage value (divided by 100) with the given number.

5The sum of angles in a triangle is:
Answer: B — 180°
The sum of all three interior angles of any triangle is always 180°. This is a fundamental theorem of Euclidean geometry. For a quadrilateral the sum is 360°.

6If x + 5 = 12, then x equals:
Answer: C — 7
To solve x + 5 = 12, subtract 5 from both sides: x = 12 − 5 = 7. This is a basic linear equation where the variable x is isolated by performing the inverse operation.

7Area of a rectangle with length 8 and breadth 5:
Answer: B — 40
Area of a rectangle = length × breadth = 8 × 5 = 40 square units. The perimeter would be 2 × (8 + 5) = 26 units. Area is always expressed in square units.

8Which number is prime?
Answer: D — 17
A prime number has exactly two factors: 1 and itself. 17 is prime (factors: 1, 17). 9 = 3×3, 15 = 3×5, 21 = 3×7 — all composite. Primes up to 20: 2, 3, 5, 7, 11, 13, 17, 19.

9Simple interest on ₹1000 at 5% for 2 years:
Answer: B — ₹100
Simple Interest (SI) = (P × R × T) / 100 = (1000 × 5 × 2) / 100 = 10000 / 100 = ₹100. P = Principal, R = Rate per annum, T = Time in years.

10The median of 3, 5, 7, 9, 11 is:
Answer: B — 7
The median is the middle value of an ordered dataset. For 3, 5, 7, 9, 11 (5 values), the middle value is the 3rd term = 7. For an even number of values, median is the average of the two middle values.
