Question : If $x^2-5\sqrt{5}x+1=0$ and $x > 0$, what is the value of $(x^3-\frac{1}{x^3})$?
Option 1: 1331
Option 2: 1364
Option 3: 1296
Option 4: 1244
Correct Answer: 1364
Solution : Given: $x^2-5\sqrt{5}x+1=0$, and $x >0$ Dividing by $x$ on both sides, we get $x-5\sqrt{5}+\frac{1}{x}=0$ ⇒ $x+\frac{1}{x}=5\sqrt{5}$ Squaring both sides, we get ⇒ $(x+\frac{1}{x})^2=(5\sqrt{5})^2=125$ We know that $(x-\frac{1}{x})^2=(x+\frac{1}{x})^2-4$ ⇒ $(x-\frac{1}{x})^2=125-4=121$ ⇒ $(x-\frac{1}{x})=11$ Now, $(x-\frac{1}{x})^3=x^3-\frac{1}{x^3}-3×x×\frac{1}{x}(x-\frac{1}{x})$ ⇒ $11^3=x^3-\frac{1}{x^3}-3×11$ ⇒ $x^3-\frac{1}{x^3}=1331+33$ $\therefore x^3-\frac{1}{x^3}=1364$ Hence, the correct answer is 1364.
Question : A man travels 434 km, partly by train and partly by steamer. He spends 8 hours more time on the steamer. If the velocity of the steamer is 25 km/hr and the velocity of the train is 65 km/hr, how much distance does he cover by steamer?
Option 1: 318 km
Option 2: 398 km
Option 3: 265 km
Option 4: 477 km
Correct Answer: 265 km
Solution : Let the time spent on the train be $x$ hours and the time spent on the steamer is $(x+8)$ hours. So, the distances travelled by train and steamer are $65x$ km and $25(x+8)$ km, respectively. According to the question, $65x + 25(x+8) = 434$
