1. If the average arithmetic mean of 8,12,15,21. x an 11 is 17 than what is x ?
- A. 3
- B. 17
- C. 15
- D. 35
Check answer and explanation
Answer: 35
Explanation As given: (8 + 12 + 15 + 21 + x + 11)/ 6 = 17 67+x = 17 x 6 67+x = 102 x = 102-67 x = 35

Answer: 35
Explanation As given: (8 + 12 + 15 + 21 + x + 11)/ 6 = 17 67+x = 17 x 6 67+x = 102 x = 102-67 x = 35
Answer: 8 times
Explanation Let's denote the original side of the cube as s. The original volume is s³. If the side is doubled, the new side is 2s. The new volume is (2s)³ = 8s³. The new volume is 8 times the original volume.
Answer: 1/cosecθ
Explanation By definition: cosecθ = 1/sinθ - So, sinθ = 1/cosecθ
Answer: 29
Explanation Let length = L Width = L - 3 Perimeter = 2(L + W) 110 = 2(L + L - 3) 110 = 2(2L - 3) 110 = 4L - 6 4L = 116 L = 29 Last verified on 11-03-2026
Answer: Incentre
Explanation The incentre is the point where the internal angle bisectors of a triangle intersect. It is the center of the incircle , which is the largest circle that fits inside the triangle.
Answer: does not exist
Explanation The factorial operation is only defined for non-negative integers, so it is not possible to compute the factorial of a negative integer. Therefore, the factorial of a negative integer does not exist.
Answer: 1
Explanation tan 45° = 1 in trigonometry.
Answer: Complementary
Explanation The range of a projectile is the same for two complementary launch angles (i.e., they add up to 90°). For example, a projectile launched at 30° and 60° will have the same range.
Answer: Chord
Explanation Straight line joining any two points of the circumference of a circle is called Chord . A chord is a line segment that joins any two points on the circumference of the circle. agm.04.03.23
Answer: Equilateral triangle
Explanation An equilateral triangle has all three sides and angles equal (each angle = 60°). It is commonly used in geometry and structural design for uniform load distribution. A scalene triangle has no equal sides and no equal angles. All sides and angles are of different lengths and measures .
