Question : If $\left (x+\frac{1}{x}\right )=5$, find the value of $\frac{6x}{x^{2}+x+1}$.
Option 1: 3
Option 3: 1
Option 4: 0
Correct Answer: 1
Solution : Given: $\left (x+\frac{1}{x} \right)=5$ ⇒ $\frac{x^2+1}{x}=5$ ⇒ $x^2+1=5x$ Adding $x$ on both sides, ⇒ $x^2+1+x=5x+x$ ⇒ $x^2+x+1=6x$ Now, put the value of $x^2+x+1=6x$ in the expression $\frac{6x}{x^{2}+x+1}$ So, $\frac{6x}{x^{2}+x+1}=\frac{6x}{6x}=1$ Hence, the correct answer is 1.

Option 1: $25$%
Option 2: $50$%
Option 3: $16\frac{2}{3}$%
Option 4: $33\frac{1}{3}$
Correct Answer: $50$%
Solution : Let the principal be Rs. $x$. Rate of interest = R% Time = 3 years Amount = $3\frac{3}{8}=3.375x$ We know, $\text{Total amount}=\text{Principal}×(1+\frac{\text{Rate}}{100})^{\text{Time}}$ $⇒3.375x = x(1 + \frac{R}{100})^{3}$ $⇒3.375 =(1 + \frac{R}{100})^{3}$ $⇒(1 + \frac{R}{100})^{3} = (1.5)^{3}$ $⇒(1 + \frac{R}{100}) = (1.5)$ $⇒\frac{R}{100}=0.5$ $\therefore R=50$% Hence,
