Question : If $a-b=8$ and $4ab=84$, then what is the value of $3a^3-3b^3$?

Option 1: 1016

Option 2: 2032

Option 3: 1018

Option 4: 3048

Team Careers360 25th Jan, 2024

Correct Answer: 3048


Solution : Given: $a-b=8$ and $4ab=84$
⇒ $ab=21$
Now, $a-b=8$
Cubing both sides we get,
⇒ $(a-b)^3=8^3$
⇒ $a^3-b^3-3ab(a-b)=512$
Putting the values, we get:
⇒ $a^3-b^3-3\times 21\times8=512$
⇒ $a^3-b^3=512+504$
⇒ $a^3-b^3=1016$
$\therefore 3a^3-3b^3 =3\times1016=3048$
Hence, the correct answer is 3048.

Question : In a $\triangle A B C, \angle B+\angle C=110^{\circ}$, then find the measure of $\angle A$.

Option 1: 90°

Option 2: 70°

Option 3: 80°

Option 4: 60°

Team Careers360 25th Jan, 2024

Correct Answer: 70°


Solution : In a $\triangle A B C, \angle B+\angle C=110^{\circ}$
The sum of angles in a triangle = 180°
⇒ $\angle A +\angle B+\angle C = 180°$
⇒ $\angle A + 110° = 180°$
⇒ $\angle A = 70°$
Hence, the correct answer is 70°.

Question : The given expression is equal to $\frac{\sin^4 A+\cos^4 A}{1-2 \sin^2 A \cos^2 A}$:

Option 1: 1

Option 2: –1

Option 3: 0

Option 4: 2

Team Careers360 25th Jan, 2024

Correct Answer: 1


Solution : $\frac{\sin^4 A+\cos^4 A}{1-2 \sin^2 A \cos^2 A}$
Since $\sin^2A+\cos^2 A=1$ and $(\sin^2A+\cos^2 A)^2=1$,
$=\frac{\sin^4 A+\cos^4 A}{(\sin^2A+\cos^2 A)^2 -2 \sin^2 A \cos^2 A}$
$= \frac{\sin^4 A+\cos^4 A}{\sin^4A+\cos^4 A -2 \sin^2 A \cos^2 A +2 \sin^2 A \cos^2 A}$
$=\frac{\sin^4 A+\cos^4 A}{\sin^4A+\cos^4 A }$
$=1$
Hence, the
