Silicon carbide also known as Carborundum is used as abrasive in manufacturing because of its hardness, purity, uniformity, and chemical composition. It is used to make various materials such as sandpapers, grinding wheels, cutting tools, hard ceramics, automobile parts, refractory linings, wear-resistant parts for pumps and rocket engines, etc. It is also characterized by its high thermal conductivity, high-temperature strength, low thermal expansion, resistance to chemical reaction, and ability to function as a semiconductor.

Let capacity of the tank be LCM of 10 and 24 =120 units
One minute work of pipe A = 120/10=12 units
One minute work of pipe B = 120/24=5 units
Let pipe A closed after t minutes. 
12t + 5 × 9 = 120
12t = 75 ⇒ t = 6¼
t= 6 minutes 15 seconds.

As some Editors are Actors and all actors are writers, so some editors are writers. Therefore, Conclusion I follow. However, conclusion II is not a definite case hence does not follows.

As detergents has cleaning properties therefore it is used to clean clothes so, assumption I mentioned how it works and assumption II mentioned its applications. Therefore both I & II implicit.

8 % 2 & 11 $ 24 & 24 # 6
After substituting signs,
8 × 2 + 11 - 24 + 24 ÷ 6
\( \Rightarrow 8\times2+11-24+\frac{24}{6} \)
\( \Rightarrow \) 16 - 13 + 4
\( \Rightarrow \) 7

It is the Montreal protocol that was amended in 1990 wherein it was decide to completely phase out CFC to prevent ozone layer depletion.

Hemocyanins are proteins that transport oxygen throughout the bodies of some invertebrate animals. These metalloproteins contain two copper atoms that reversibly bind a single oxygen molecule (O ₂). They are second only to hemoglobin in frequency of use as an oxygen transport molecule.
