The logic here is – (The first number × 4) + (The third number × 5) = The second number (2, 28, 4)→(2 × 4) + (4 × 5) = 8 + 20 = 28 (3,
Question : Directions: Two statements are given followed by three conclusions numbered I, II, and III. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements.

Question : Each interior angle of a regular polygon is $18^{\circ}$ more than eight times an exterior angle. The number of sides of the polygon is:
Option 1: 10
Option 2: 15
Option 3: 20
Option 4: 25
Correct Answer: 20
Solution : The sum of the exterior angles of a polygon = $360^{\circ}$ Let the number of sides of the regular polygon be $n$. Each exterior angle = $\frac{360^\circ}{n}$ Each interior angle = $\frac{(n-2)\times 180^\circ}{n}$ According to the question, $\frac{360^\circ}{n}\times 8 + 18^\circ=\frac{(n-2)\times 180^\circ}{n}$ ⇒ $2880 +

Question : A right circular cylinder of the maximum possible size is cut out from a solid wooden cube. The remaining material of the cube is what percentage of the original cube? (Take $\pi=3.14$)
Option 1: 22.4
Option 2: 21.5
Option 3: 22.8
Option 4: 21.8
Correct Answer: 21.5
Solution : Let the dimensions of the wooden cube = $a \times a \times a$ The volume of the wooden cube = $a^3$ The diameter of the cylinder and its height = $a$ The volume of the cylinder = $\pi r ^2 h$, where $r$ and $h$
