Question : If $(4 \sin \theta+5 \cos \theta)=3$, then the value of $(4 \cos \theta-5 \sin \theta)$ is:

Option 1: $3 \sqrt{2}$

Option 2: $4 \sqrt{2}$

Option 3: $2 \sqrt{3}$

Option 4: $2 \sqrt{5}$

Team Careers360 14th Jan, 2024

Correct Answer: $4 \sqrt{2}$


Solution : $(4 \sin \theta+5 \cos \theta)=3$
Squaring both sides, we get,
$⇒16 \sin^2 \theta+25 \cos^2 \theta+40\sin\theta\cos\theta=9$
$⇒16(1-\cos^2 \theta)+25(1-\sin^2 \theta) + 40\sin\theta\cos\theta= 9$
$⇒16-16\cos^2\theta+25-25\sin^2\theta+40\sin\theta\cos\theta=9$
$⇒16\cos^2\theta+25\sin^2\theta-40\sin\theta\cos\theta=16+25-9$
$⇒(4\cos\theta)^2+(5\sin\theta)^2-2\times 5\sin\theta \times 4\cos\theta=32$
$⇒(4\cos\theta - 5\sin\theta)^2 = 32$
$⇒(4\cos\theta - 5\sin\theta) = \sqrt{32}=4\sqrt{2}$
Hence, the correct answer is $4\sqrt{2}$.

Question : If $\cot^2θ = 1 - e^2$, then the value of $\operatorname{cosec} θ + \cot^3θ \sec θ$ is:

Option 1: $\left(2-{e}^2\right)^ \frac{1}{2}$

Option 2: $\left(1-{e}^2\right)^ \frac{3}{2}$

Option 3: $\left(1-{e}^2\right)$

Option 4: $\left(2-{e}^2\right) ^\frac{3}{2}$

Team Careers360 17th Jan, 2024

Correct Answer: $\left(2-{e}^2\right) ^\frac{3}{2}$


Solution : Given,
$\cot^2θ = 1 - e^2$
Consider,
$\operatorname{cosec} θ + \cot^3θ \sec θ$
$=\frac{1}{\sinθ} + \frac{\cos^3θ}{\sin^3θ}\frac1{\cosθ}$
$=\frac{\sin^2θ+\cos^2θ}{\sin^3θ}$
$=\frac{1}{\sin^3θ}$ [As $\sin^2θ+\cos^2θ=1$]
$=\operatorname{cosec^3}θ$
Also, we know that,
$\operatorname{cosec^2}θ=1+\cot^2θ$
⇒ $\operatorname{cosec^2}θ=1+1-e^2$
⇒ $\operatorname{cosec^2}θ=2-e^2$
⇒ $\operatorname{cosec}θ=(2-e^2)^{\frac12}$
⇒ $\operatorname{cosec^3}θ=(2-e^2)^{\frac32}$
Hence, the correct answer is $(2-e^2)^{\frac32}$.

Question : If 42 persons consume 144 kg of wheat in 15 days, how many days will 30 persons consume 48 kg of wheat?

Option 1: 8 days

Option 2: 7 days

Option 3: 12 days

Option 4: 6 days

Team Careers360 13th Jan, 2024

Correct Answer: 7 days


Solution : Given: 42 persons can consume 144 kg of wheat in 15 days.
Let in $x$ days 30 persons consume 48 kg of wheat.
We know that $\frac{M1D1}{W1}=\frac{M2D2}{W2}$
According to the question,
$\frac{42×15}{144}=\frac{30×x}{48}$
⇒ $x=7$
Hence, the correct answer is 7 days.
