Question : The volume of a conical tent is 1232 m3 and the area of its base is 154 sq m. Find the length of the canvas required to build the tent, if the canvas is 2 m in width. (Take $\pi=\frac{22}{7}$)
Option 1: 270 m
Option 2: 272 m
Option 3: 276 m
Option 4: 275 m
Correct Answer: 275 m
Solution : Let the radius be $r$ and the height be $h$. Area of the base = 154 sq m ⇒ $\pi r^2$ = 154 $\therefore r$ = 7 m Volume of cone = $\frac{1}{3}\pi r^2 h$ ⇒ $1232 =\frac{1}{3}×\frac{22}{7}×7×7×h$ $\therefore h = 24$ m Slant
Question : A, B, and C run simultaneously, starting from a point, around a circular track of length 1200 m, at respective speeds of 2 m/s, 4 m/s, and 6 m/s. A and B run in the same direction, while C runs in the opposite direction to the other two. After how much time will they meet for the first time?
Option 1: 10 minutes
Option 2: 9 minutes
Option 3: 12 minutes
Option 4: 11 minutes
Correct Answer: 10 minutes
Solution : Circular Track length = 1200 m Speed of A = 2 m/s Speed of B = 4 m/s Speed of C = 6 m/s The relative speed of A and B = 4 – 2 = 6 m/s The relative speed of A and

Option 1: 8 - 7 + 3 x 5 = 35
Option 2: 7 x 8 + 6 - 9 = 25
Option 3: 6 + 8 x 2 - 7 = 0

Correct Answer: 6 + 8 x 2 - 7 = 0
Solution : We have to interchange + and -, 8 and 7, in all the options.
Option first: 8 - 7 + 3 x 5 = 35
8 + 7 - 3 x 5 = 33. Here, the equation

Question : If $\left(x^2 - \frac{1}{x^2}\right) = 4 \sqrt{6}$ and $x>1$, what is the value of $\left(x^3 - \frac{1}{x^3}\right)?$
Option 1: $20 \sqrt{2}$
Option 2: $24 \sqrt{2}$
Option 3: $18 \sqrt{2}$
Option 4: $22 \sqrt{2}$
Correct Answer: $22 \sqrt{2}$
Solution : Given: $x^2 -\frac{1}{x^2} = 4\sqrt6$ Squaring both sides we get, ⇒ $x^4 +\frac{1}{x^4} - 2 = 96$ ⇒ $x^4 +\frac{1}{x^4}+2 = 98+2$ ⇒ $ (x^2+\frac{1}{x^2})^2 =100$ ⇒ $x^2 +\frac{1}{x^2} = 10$ ---------------(1) ⇒ $x^2 +\frac{1}{x^2} -2= 10-2$ ⇒ $(x-\frac{1}{x})^2=8$ ⇒ $(x-\frac{1}{x}) = 2\sqrt2$ ----------------(2)
