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

Team Careers360 22nd Jan, 2024

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

Team Careers360 22nd Jan, 2024

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 4: 729

Team Careers360 18th Jan, 2024

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: $68^\circ$

Team Careers360 17th Jan, 2024

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
