Question : Raju ate $\frac{3}{8}$th part of a pizza and Adam ate $\frac{3}{10}$th part of the remaining pizza. Then Renu ate $\frac{4}{7}$th part of the pizza that was left. What fraction of the pizza is still left?

Option 1: $\frac{5}{12}$

Option 2: $\frac{1}{4}$

Option 3: $\frac{1}{8}$

Option 4: $\frac{3}{16}$

Team Careers360 25th Jan, 2024

Correct Answer: $\frac{3}{16}$


Solution : Let the total pizza be 1 part.
Raju ate $\frac{3}{8}$th part of it.
Remaining Part of the pizza $=(1 - \frac{3}{8})=\frac{5}{8}$ part
Adam ate $\frac{3}{10}$th part of the remaining pizza.
So, Adam ate $(\frac{5}{8} × \frac{3}{10}) = \frac{15}{80} = \frac{3}{16}$ part of the total pizza

Question : If h, c, v are respectively the height, curved surface area, and volume of a right circular cone, then the value of $3\pi v h^{3}-c^{2}h^{2}+9v^{2}$ is:

Option 1: 2

Option 2: –1

Option 3: 1

Option 4: 0

Team Careers360 22nd Jan, 2024

Correct Answer: 0


Solution : Let $r$ be the radius, $h$ be the height, $l$ be the slant height and $c$ be the curved surface area of the cone.
We know, $l=\sqrt{r^2+h^2},v=\frac{1}{3}\pi r^2 h,$ and $c=\pi r l$
According to the question:
$3\pi v h^{3}-c^{2}h^{2}+9v^{2}$
= $3\pi ×\frac{1}{3}\pi r^2 h×
