Question : If $(x+\frac{1}{x})$ = 5, then the value of $\frac{5x}{x^{2}+5x+1}$ is:
Option 1: $\frac{1}{3}$
Option 2: $\frac{1}{4}$
Option 3: $\frac{1}{2}$
Option 4: $\frac{1}{5}$
Correct Answer: $\frac{1}{2}$
Solution : Given: $(x+\frac{1}{x})$ = 5 ⇒ $x^2+1= 5x$ Now, $\frac{5x}{x^{2}+5x+1}$ = $\frac{5x}{x^{2}+1+5x}$ = $\frac{5x}{5x+5x}$ = $\frac{5x}{10x}$ = $\frac{1}{2}$ Hence, the correct answer is $\frac{1}{2}$.
Question : A bus moving at 40 km/hr covers a distance in 6 hours 15 minutes. If it travels the same distance at 50 km/hr, how long will it take to cover the distance?
Option 1: 2 hours
Option 2: 6 hours
Option 3: 4 hours
Option 4: 5 hours
Correct Answer: 5 hours
Solution : Speed = 40 km/hr Time = 6 hr 15 min = 6.35 hours Distance = Speed $\times$ Time = 40 $\times$ 6.25 ⇒ Distance = 250 km Now, speed = 50 km/hr Distance is the same as the distance covered by the bus with
