Question : If $2x+\frac{1}{3x}$ = 5, then the value of $\frac{5x}{6x^{2}+20x+1}$ is:
Option 1: $\frac{1}{4}$
Option 2: $\frac{1}{6}$
Option 3: $\frac{1}{5}$
Option 4: $\frac{1}{7}$
Correct Answer: $\frac{1}{7}$
Solution : Given: $2x+\frac{1}{3x} = 5$ By cross-multiplying, ⇒ $\frac{6x^{2}+1}{3x} = 5$ ⇒ $6x^{2} + 1 = 15x$ ------------(i) Now, $\frac{5x}{6x^{2}+20x+1}$ = $\frac{5x}{15x+20x}$ = $\frac{5x}{35x}$ = $\frac{1}{7}$ Hence, the correct answer is $\frac{1}{7}$.

Question : The average number of runs scored by a cricket player in 11 innings is 63, the average of his first six innings is 60, and the average of his last six innings is 65. Find the runs scored by him in the sixth inning.
Option 1: 60
Option 2: 54
Option 3: 67
Option 4: 57

Solution : Given: The average score of runs in 11 innings is 63. So, the total number of runs = (11 × 63) = 693 The average score of the first 6 innings is 60. So, the total runs in the first 6 innings is 6 ×
Question : Which of the following statement(s) is/are TRUE? I. $\frac{2}{3\sqrt5}<\frac{3}{2\sqrt5}<\frac{5}{4\sqrt3}$ II. $\frac{3}{2\sqrt5}<\frac{2}{3\sqrt3}<\frac{7}{4\sqrt5}$
Option 1: Only I
Option 2: Only II
Option 3: Both I and II
Option 4: Neither I nor II
Correct Answer: Only I
Solution : Let's simplify the fractions in each statement to see if they are true: I. $\frac{2}{3\sqrt5}<\frac{3}{2\sqrt5}<\frac{5}{4\sqrt3}$ Rationalising each fraction, we get: $\frac{2\sqrt5}{15}<\frac{3\sqrt5}{10}<\frac{5\sqrt3}{12}$ Converting these fractions to decimal form, we get: 0.29 < 0.47 < 0.72, where $\sqrt5$ = 2.236 and $\sqrt3$ = 1.732 So, Statement
