Geology QUESTION #10636

Question 7

Quartzite is produced by the metamorphism of which parent rock (protolith)?

Shale
Limestone
Both shale and limestone
Sandstone✔️

Correct Answer Logic:

Quartzite is a metamorphic rock formed by the metamorphism of quartz-rich sandstone. During metamorphism, quartz grains recrystallise and interlock, producing a hard, non-foliated rock. Shale metamorphoses to slate, phyllite, schist, or gneiss. Limestone metamorphoses to marble. The key protolith for quartzite is sandstone (or chert for some varieties).

Correct Answer Logic:

$\left(x + \dfrac{1}{x}\right)^2 = x^2 + 2 + \dfrac{1}{x^2}$. So $25 = x^2 + 2 + \dfrac{1}{x^2} \Rightarrow x^2 + \dfrac{1}{x^2} = 23$.

Aptitude QUESTION #10952

Question 16

A staircase has 12 steps, each 18 cm high and 28 cm wide (tread). What is the slope angle of the staircase? (Use $\tan^{-1}(0.643) \approx 33°$

\(32°\
\(33°\✔️
\(37°\
\(45°\

Correct Answer Logic:

Slope angle \(\theta = \tan^{-1}\left(\dfrac{\text{rise}}{\text{run}}\right) = \tan^{-1}\left(\dfrac{18}{28}\right) = \tan^{-1}(0.643) \approx 33°\

In architectural design, comfortable stair angles range from 25° to 40°. The ideal is around 30°–35°.

This is why building codes specify maximum riser heights (typically 190 mm) and minimum tread depths (typically 250 mm) — to keep the angle in a safe, comfortable range.
