Question : Direction: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. 'F' can be represented by 30, 23, etc., and 'N' can be represented by 97, 89, etc. Similarly, you have to identify the set for the given word.

Question : On the ground, there is a vertical tower with a flagpole on its top. At a point 9 metres away from the foot of the tower, the angles of elevation of the top and bottom of the flagpole are 60° and 30°, respectively. The height of the flagpole is:
Option 1: $5\sqrt{3}$ metres
Option 2: $6\sqrt{3}$ metres
Option 3: $6\sqrt{2}$ metres
Option 4: $6\sqrt{5}$ metres
Correct Answer: $6\sqrt{3}$ metres
Solution : In the figure, the flagpole is AB, BC is the tower and CD is the base. In $\triangle$ACD, $⇒\tan 60°=\frac{\text{AC}}{\text{DC}}$ $⇒\sqrt{3}=\frac{\text{AC}}{9}$ $⇒\text{AC}=9\sqrt{3}$ metres In $\triangle$BCD, $⇒\tan 30°=\frac{\text{BC}}{\text{DC}}$ $⇒\frac{1}{\sqrt{3}}=\frac{\text{BC}}{9}$ $⇒\text{BC}=\frac{9}{\sqrt{3}} = 3\sqrt{3}$ metres $⇒\text{AC = AB + BC}$ $⇒\text{AB = AC – BC}$ $⇒\text{AB} =

Question : Simplify the following: $\frac{\cos x-\sqrt{3} \sin x}{2}$
Option 1: $\cos \left(\frac{\pi}{3}-x\right)$
Option 2: $\sin \left(\frac{\pi}{3}+x\right)$
Option 3: $\cos \left(\frac{\pi}{3}+x\right)$
Option 4: $\sin \left(\frac{\pi}{3}-x\right)$
Correct Answer: $\cos \left(\frac{\pi}{3}+x\right)$
Solution : Given, $\frac{\cos x-\sqrt{3} \sin x}{2}$ = $\frac{1}{2} \cos x-\frac{\sqrt3}{2}\sin x$ = $\cos x \cos \frac{\pi}{3} - \sin \frac{\pi}{3} \sin x$ [$\because\cos \frac{\pi}{3}=\frac{1}{2}$ and $\sin \frac{\pi}{3}=\frac{\sqrt3}{2}$] = $\cos( \frac{\pi}{3}+x)$ Hence, the correct answer is $\cos( \frac{\pi}{3}+x)$.
