Question : If $(a^3+b^3+c^3-3 a b c)=405$ and $(a-b)^2+(b-c)^2+(c-a)^2=54$, find the value of $(a + b + c)$.
Option 1: 15
Option 2: 45
Option 3: 9
Option 4: 27
Correct Answer: 15
Solution : $(a-b)^2+(b-c)^2+(c-a)^2=54$ ⇒ $2(a^2+b^2+c^2-ab-bc-ac)=54$ ⇒ $(a^2+b^2+c^2-ab-bc-ac)=27$ Also, we know that $(a^3+b^3+c^3-3 a b c) = (a+b+c)(a^2+b^2+c^2-ab-bc-ac)$ Substituting the values, ⇒ $405 = 27×(a+b+c)$ ⇒ $a+b+c = 15$ Hence, the correct answer is 15.
Question : If the selling price of 318 articles is equal to the cost price of 212 articles, then what is the loss percentage?
Option 1: $20$
Option 2: $33\frac{1}{3}$
Option 3: $40$
Option 4: $33\frac{2}{3}$
Correct Answer: $33\frac{1}{3}$
Solution : Let the cost price of 1 article be Rs. $x$. Selling price of 1 article $=\frac{212}{318}x$ Loss percentage $=\frac{x-\frac{212}{318}x}{x} × 100 = 33\frac{1}{3}$% Hence, the correct answer is $33\frac{1}{3}$.
