Question : The value of $\frac{\sqrt{72}\times \sqrt{363}\times \sqrt{175}}{\sqrt{32}\times \sqrt{147}\times \sqrt{252}}$ is:
Option 1: $\frac{55}{42}$
Option 2: $\frac{45}{56}$
Option 3: $\frac{45}{28}$
Option 4: $\frac{55}{28}$
Correct Answer: $\frac{55}{28}$
Solution : $\frac{\sqrt{72}\times \sqrt{363}\times \sqrt{175}}{\sqrt{32}\times \sqrt{147}\times \sqrt{252}}$ $=\sqrt{\frac{72}{32}} \times \sqrt{\frac{363}{147}} \times \sqrt{\frac{175}{252}}$ Simplifying each square root, $=\sqrt{\frac{9}{4}} \times \sqrt{\frac{121}{49}} \times \sqrt{\frac{25}{36}}$ $=\frac{3}{2} \times \frac{11}{7} \times \frac{5}{6} = \frac{55}{28}$ Hence, the correct answer is $\frac{55}{28}$.

Question : Find the value of $\frac{\cos^{2}25^\circ-\sin^{2}65^\circ}{\cos^{2}25^\circ+\sin^{2}65^\circ}$
Option 1: $\frac{1}{2}$
Option 2: $1$
Option 3: $–1$
Option 4: $0$
Correct Answer: $0$
Solution : Given: $\frac{\cos^{2}25^\circ-\sin^{2}65^\circ}{\cos^{2}25^\circ+\sin^{2}65^\circ}$ = $\frac{\cos^{2}25^\circ-\sin^{2}(90^\circ-25^\circ)}{\cos^{2}25^\circ+\sin^{2}(90^\circ-25^\circ)}$ = $\frac{\cos^{2}25°-\cos^{2}25°}{\cos^{2}25°+\cos^{2}25°}$ = $\frac{0}{2\cos^{2}25^\circ}$ = $0$ Hence, the correct answer is $0$.
Question : Which of the following statements is true? I. $\frac{1}{2}+\frac{1}{6}+\frac{1}{12}+\ldots \ldots \frac{1}{110}<\frac{5}{6}$ II. $\frac{1}{3}+\frac{1}{15}+\frac{1}{35}+\ldots \ldots \frac{1}{143}>\frac{7}{13}$
Option 1: Only I
Option 2: Both I and II
Option 3: Only II
Option 4: Neither I nor II
Correct Answer: Neither I nor II
Solution : Statement I: $\frac{1}{2}+\frac{1}{6}+\frac{1}{12}+\ldots \ldots \frac{1}{110}<\frac{5}{6}$ Expand LHS $⇒\frac{1}{2}+\frac{1}{2\times{3}}+\frac{1}{3\times{4}}+\ldots \ldots \frac{1}{10\times{11}}<\frac{5}{6}$ $⇒\frac{1}{2}+\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-\frac{1}{4}+\ldots \ldots \frac{1}{10}-\frac{1}{11}<\frac{5}{6}$ $⇒1-\frac{1}{11}<\frac{5}{6}$ $⇒\frac{10}{11}<\frac{5}{6}$ which is wrong, So, statement I is incorrect. Statement II: $\frac{1}{3}+\frac{1}{15}+\frac{1}{35}+\ldots \ldots \frac{1}{143}>\frac{7}{13}$ $⇒\frac{1}{3}+\frac{1}{3\times5}+\frac{1}{5\times7}+\ldots \ldots \frac{1}{11\times13}>\frac{7}{13}$ $⇒\frac{1}{3}+\frac{2}{2}[\frac{1}{3\times5}+\frac{1}{5\times7}+\ldots \ldots \frac{1}{11\times13}]>\frac{7}{13}$ $⇒\frac{1}{3}+\frac{1}{2}[\frac{1}{3}-\frac{1}{5}+\frac{1}{5}-\frac{1}{7}+\ldots \ldots \frac{1}{11}-\frac{1}{13}]>\frac{7}{13}$ $⇒\frac{1}{3}+\frac{1}{2}[\frac{1}{3}-\frac{1}{13}]>\frac{7}{13}$ $⇒\frac{1}{3}+\frac{5}{39}>\frac{7}{13}$ $⇒\frac{6}{13}>\frac{7}{13}$ which is
