Question : If $a^2+b^2+c^2+216=12(a+b-2 c)$, then $\sqrt{a b-b c+c a}$ is:
Option 1: 8
Option 2: 3
Option 3: 6
Option 4: 4
Correct Answer: 6
Solution : Given: $a^2+b^2+c^2+216=12(a+b-2 c)$ Rearranging and simplifying ⇒ $a^2 - 12a + b^2 - 12b + c^2 + 24c + 216 = 0$ ⇒ $a^2 - 12a + 36 + b^2 - 12b + 36 + c^2 + 24c + 144 = 0$ ⇒ $(a -

Question : If the angle of elevation of the Sun changes from 30° to 45°, the length of the shadow of a pillar decreases by 20 metres. The height of the pillar is:
Option 1: $20(\sqrt{3}-1)$ m
Option 2: $20(\sqrt{3}+1)$ m
Option 3: $10(\sqrt{3}-1)$ m
Option 4: $10(\sqrt{3}+1)$ m
Correct Answer: $10(\sqrt{3}+1)$ m
Solution : In $\Delta$ ABC $\tan 45°=\frac{AB}{BC}$ ⇒ $1=\frac{h}{BC}$ ⇒ $BC=h=AB$ In $\Delta$ ABD $\tan 30°=\frac{AB}{BD}$ ⇒ $\frac{1}{\sqrt3}=\frac{h}{h+20}$ ⇒ $h+20=h\sqrt{3}$ ⇒ $h=\frac{20}{\sqrt{3}–1}$ ⇒ $h=\frac{20}{\sqrt{3}–1}×\frac{\sqrt{3+1}}{\sqrt{3+1}}$ ⇒ $h=10(\sqrt{3}+1)$ m Hence, the correct answer is $10(\sqrt{3}+1)$ m.
Question : Directions: In the following question a series is given, with one number missing. select the missing number from the given alternatives. 4, 16, 36, 64, ?
Option 1: 81
Option 2: 121
Option 3: 100
Option 4: 729
Correct Answer: 100
Solution : Given: 4, 16, 36, 64,?
Each term is obtained by the squaring of consecutive even numbers – 22 = 4; 42 = 16; 62 = 36; 82 = 64; 102 = 100
So, 100 is the missing term in the
Question : In $\triangle \mathrm{ABC}, \mathrm{BD} \perp \mathrm{AC}$ at D. E is a point on BC such that $\angle \mathrm{BEA}=x^{\circ}$. If $\angle \mathrm{EAC}=62^{\circ}$ and $\angle \mathrm{EBD}=60^{\circ}$, then the value of $x$ is:
Option 1: $92^\circ$
Option 2: $78^\circ$
Option 3: $76^\circ$
Option 4: $68^\circ$
Correct Answer: $92^\circ$
Solution : In $\triangle AOD$, $\angle AOD + \angle ADO + \angle DAO = 180^\circ$ ⇒ $\angle AOD + 90^\circ + 62^\circ = 180^\circ$ ⇒ $\angle AOD = 180^\circ - 152^\circ$ ⇒ $\angle AOD = 28^\circ$ $\because \angle AOD$ and $\angle EOB$ are vertical opposite angles, $\angle
