Question : A solid metallic sphere of radius x cm is melted and then drawn into 126 cones each of radius 3.5 cm and height 3 cm. There is no wastage of material in this process. What is the value of $x$?

Option 1: 10.5

Option 2: 3.5

Option 3: 7

Option 4: 21

Team Careers360 22nd Jan, 2024

Correct Answer: 10.5


Solution : The volume of the sphere = $\frac {4}{3}\pi r^3$,
Volume of a cone = $\frac{1}{3}\pi r^2h$, where $r$ = radius, $h$ = height
According to the question,
$\frac {4}{3}\pi r^3= 126 × \frac{1}{3}\pi r^2h$
⇒ $x^{3} = \frac{126}{4} × 3.5 × 3.5 × 3$

Question : The total surface area of a hemisphere is 41.58 sq. cm. Find its curved surface area.

Option 1: 27.72 sq. cm.

Option 2: 55.44 sq. cm.

Option 3: 9.24 sq. cm.

Option 4: 13.86 sq. cm.

Team Careers360 25th Jan, 2024

Correct Answer: 27.72 sq. cm.


Solution : The curved surface area of a hemisphere = $2\pi r^2$
The total surface area of a hemisphere = $3\pi r^2$
⇒ $41.58=3\pi r^2$
⇒ $3\pi r^2×\frac{2}{3}=41.58×\frac{2}{3}$
$\therefore 2\pi r^2=27.72$ sq. cm.
Hence, the correct answer is 27.72 sq. cm.

Question : A and B can do a piece of work in 18 days, B and C in 24 days and A and C in 36 days. Working together, they can do the work in:

Option 1: 12 days

Option 2: 13 days

Option 3: 16 days

Option 4: 26 days

Team Careers360 19th Jan, 2024

Correct Answer: 16 days


Solution : One day work of (A + B) = $\frac{1}{18}$
One day work of (B + C) = $\frac{1}{24}$
One day work of (C + A) = $\frac{1}{36}$
Combined work = ($\frac{1}{A+B}+\frac{1}{B+C}+\frac{1}{C+A}$) = ($\frac{1}{18}+\frac{1}{24}+\frac{1}{36}$)
⇒ 2(A + B + C) = $\frac{4+3+2}{72}$ = $\frac{9}{72}$ =
