Question : Given that $\sqrt3=1.732$, the value of $\frac{3+\sqrt6}{5\sqrt3-2\sqrt{12}-\sqrt{32}+\sqrt{50}}$ is:

Option 1: 4.899

Option 2: 2.551

Option 3: 1.414

Option 4: 1.732

Team Careers360 25th Jan, 2024

Correct Answer: 1.732


Solution : Given:
$\sqrt{3}=1.732$
$\frac{3+\sqrt{6}}{5\sqrt{3}-2\sqrt{12}-\sqrt{32}+\sqrt{50}}$
Now evaluate:
$= \frac{3+\sqrt{6}}{5\sqrt{3}-2\sqrt{4\times3}-\sqrt{16\times2}+\sqrt{25\times2}}$
$=\frac{3+\sqrt{6}}{5\sqrt{3}-4\sqrt{3}-4\sqrt{2}+5\sqrt{2}}$
$=\frac{3+\sqrt{6}}{5(\sqrt{3}+\sqrt{2})-4(\sqrt{3}+\sqrt{2})}$
$=\frac{3+\sqrt{6}}{\sqrt{3}+\sqrt{2}}$
Now multiply and divide with $\sqrt{3}-\sqrt{2}.$
$=\frac{3+\sqrt{6}}{\sqrt{3}+\sqrt{2}}\times\frac{\sqrt{3}-\sqrt{2}}{\sqrt{3}-\sqrt{2}}$
$=\frac{3\sqrt{3}-3\sqrt{2}+\sqrt{18}-\sqrt{12}}{3-2}$
$=\frac{3\sqrt{3}-3\sqrt{2}+\sqrt{9\times2}-\sqrt{4\times3}}{1}$
$=3\sqrt{3}-3\sqrt{2}+3\sqrt{2}-2\sqrt{3}$
$=3\sqrt{3}-2\sqrt{3}$
$=\sqrt{3}(3-2)$
$=\sqrt{3}$
$=1.732$
Hence, the correct answer is 1.732.

Question : The value of $\left(\operatorname{cosec}^2 B-1\right)\left(\sec ^2 B-1\right)$ is:

Option 1: 4

Option 2: 3

Option 3: 2

Option 4: 1

Team Careers360 25th Jan, 2024

Correct Answer: 1


Solution : Given: $\left(\operatorname{cosec}^2 B-1\right)\left(\sec ^2 B-1\right)$
We know that
$\operatorname{cosec}^2 B = 1 + \cot^2 B$
$\sec^2 B = 1 + \tan^2 B$
$\left(\operatorname{cosec}^2 B-1\right)\left(\sec ^2 B-1\right) = \cot^2 B\times\tan^2 B$.
$=\cot^2 B \times \tan^2 B = \frac{1}{\tan^2 B}\times\tan^2 B = 1$
Hence, the correct answer

Question : If $p-\frac{1}{p}=6$, then what is the value of $p^4+\frac{1}{p^4}$?

Option 1: 1562

Option 2: 1432

Option 3: 1442

Option 4: 1444

Team Careers360 25th Jan, 2024

Correct Answer: 1442


Solution : $\mathrm{p}-\frac{1}{\mathrm{p}}=6$
Squaring both sides, we get,
$⇒p^2+\frac{1}{p^2}-2(p)(\frac{1}{p})=36$
$⇒p^2+\frac{1}{p^2}-2=36$
$⇒p^2+\frac{1}{p^2}=38$
Squaring both sides again, we get,
$⇒p^4+\frac{1}{p^4}+2(p^2)(\frac{1}{p^2})=1444$
$⇒p^4+\frac{1}{p^4}+2=1444$
$\therefore p^4+\frac{1}{p^4}=1442$
Hence, the correct answer is 1442.

Question : The compound interest received on INR 18,000 for 2 years is INR 7,920 when the interest is compounded annually. What is the rate of interest per annum?

Option 1: 15%

Option 2: 12.5%

Option 3: 20%

Option 4: 25%

Team Careers360 25th Jan, 2024

Correct Answer: 20%


Solution : Given: Compound interest = INR 7920
Principal = INR 18,000
Time = 2 years
Compound interest $= \text{Principal}×((1+\frac{\text{Rate}}{100})^{\text{Time}}-1)$
⇒ $7920=18000×((1+\frac{\text{Rate}}{100})^{2}-1)$
⇒ $\frac{7920}{18000}=((1+\frac{\text{Rate}}{100})^{2}-1)$
⇒ $\frac{11}{25}+1=(1+\frac{\text{Rate}}{100})^{2}$
⇒ $\frac{36}{25}=(1+\frac{\text{Rate}}{100})^{2}$
⇒ $\frac{6}{5}=1+\frac{\text{Rate}}{100}$
⇒ $\frac{6}{5}-1=\frac{\text{Rate}}{100}$
⇒ $\frac{1}{5}=\frac{\text{Rate}}{100}$
$\therefore$ Rate $= 20$%
Hence, the correct answer is 20%.
