Correct Answer: 37
Solution : Given: 2[3.5 × 3.5 + 2.5 × 2.5] = 2 × [12.25 + 6.25] = 2 × 18.5 = 37 Hence, the correct answer is 37.
Question : In a camp, there are tents of the same shape and size. Each tent is cylindrical up to a height of 4 m and conical above it. The diameters of the bases of the cylinder and the cone are both 10.5 m and the slant height of the conical part is 10 m. If a total of 3861 m2 canvas is used in making all the tents, then how many tents are there in the camp? [ Use $\pi-\frac{22}{7}$ ]
Option 1: 11
Option 2: 7
Option 3: 19
Option 4: 13
Correct Answer: 13
Solution : Given: Radius of the base = $\frac{10.5}{2}$ = 5.25 m Height = 4 m Slant height = 10 m The curved surface area of each tent = curved surface area of the cylindrical part + curved surface area of the conical part = $2\pi rh

Question : A man goes to a place on the car at a speed of 144 km/hr and comes back at a lower speed. If the average speed is 60 km/hr in total, then find his returning speed.
Option 1: 40.05 km/hr
Option 2: 37.89 km/hr
Option 3: 33.33 km/hr
Option 4: 22.25 km/hr
Correct Answer: 37.89 km/hr
Solution : Let the return speed of man be $x$. Given, Average speed = 60 km/hr As we know, Average speed = $\frac{2xy}{x + y}$, where $x$ and $y$ are the speeds resp. ⇒ $60 = \frac{2 × 144 × x}{144 + x}$ ⇒ $144+ x

Question : If $A:B: C=2:3:4$, then what will be the value of $\frac{A}{B}:\frac{B}{C}:\frac{C}{A}$?
Option 1: $9: 5: 36$
Option 2: $8: 7: 25$
Option 3: $8: 9: 24$
Option 4: $12: 10: 13$
Correct Answer: $8: 9: 24$
Solution : Let's denote $k$ as a constant. Given that $A :B : C = 2 :3 :4$ ⇒ $A = 2k,B = 3k,$ and $C = 4k$ So, $\frac{A}{B} = \frac{2k}{3k}=\frac{2}{3}$ ⇒ $\frac{C}{D} = \frac{3k}{4k}=\frac{3}{4}$ ⇒ $\frac{C}{A} = \frac{4k}{2k} = \frac{2}{1}$ So, the values
