Question : Direction: The following bar graph shows the production of table fans in a factory for one week. Study the bar graph and answer the given question.

The maximum production exceeds the minimum production by:

Option 1: 400

Option 2: 420

Option 3: 500

Option 4: 540

Team Careers360 24th Jan, 2024

Correct Answer: 420


Solution : The provided bar graph shows that the maximum production is 540 and the minimum production is 120, respectively.
Difference = Maximum production – Minimum production = 540 – 120 = 420
Hence, the correct answer is 420.

Question : A, B, and C are employed to do a piece of work for INR 5,290. A and B together are supposed to do $\frac{19}{23}$ of the work and B and C together $\frac{8}{23}$ of the work. Then A should be paid:

Option 1: INR 4,250

Option 2: INR 3,450

Option 3: INR 1,950

Option 4: INR 2,290

Team Careers360 20th Jan, 2024

Correct Answer: INR 3,450


Solution : Part of work done by A and B together = $\frac{19}{23}$ of total work
Part of work done by B and C together = $\frac{8}{23}$ of total work
Part of the work done by A alone
= Total work – Part of work done

Question : If $m-n=2$ and $mn=15,(m,n>0)$ , then the value of $(m^2-n^2)(m^3-n^3)$ is:

Option 1: 1856

Option 2: 1658

Option 3: 1586

Option 4: 1568

Team Careers360 15th Jan, 2024

Correct Answer: 1568


Solution : Given:
$m-n=2$ and $mn=15,(m,n>0)$
$(m-n)^2=2^2$
⇒ $m^2+n^2-2mn=4$
⇒ $m^2+n^2=4+(2×15)=34$
⇒ $m^2+n^2+30=34+30$ [adding 30 to both sides]
⇒ $m^2+n^2+2mn=64$ [as, $mn=15$]
⇒ $(m+n)^2=8^2$
⇒ $m+n=8$
Now, $(m^2-n^2)(m^3-n^3)$
= $(m+n)(m-n) (m-n)(m^2+mn+n^2)$
= $8×2×2×(34+15)$
= $1568$
Hence, the correct answer is 1568.

Question : Which of the following is equal to $[\frac{\tan \theta+\sec \theta–1}{\tan \theta–\sec \theta+1}]$?

Option 1: $\frac{1+\sin \theta}{\cos \theta}$

Option 2: $\frac{1+\tan \theta}{\cot \theta}$

Option 3: $\frac{1+\cot \theta}{\tan \theta}$

Option 4: $\frac{1+\cos \theta}{\sin \theta}$

Team Careers360 17th Jan, 2024

Correct Answer: $\frac{1+\sin \theta}{\cos \theta}$


Solution : Given: The given trigonometric expression is $[\frac{\tan \theta+\sec \theta–1}{\tan \theta–\sec \theta+1}]$.
Use the trigonometric identity, $\sec^2\theta–\tan^2\theta=1$
⇒ $[\frac{\tan \theta+\sec \theta–(\sec^2\theta–\tan^2\theta)}{\tan \theta–\sec \theta+1}]=[\frac{(\tan \theta+\sec \theta)(1–\sec\theta+\tan \theta)}{\tan \theta–\sec \theta+1}$
$=\tan \theta+\sec \theta=\frac{1+\sin \theta}{\cos \theta}$
Hence, the correct answer is $\frac{1+\sin \theta}{\cos \theta}$.

Question : If $\cos \theta=\frac{\sqrt{3}}{2}$, then $\tan ^2 \theta \cos ^2 \theta=?$

Option 1: $\frac{1}{\sqrt{3}}$

Option 2: $\frac{1}{4}$

Option 3: $\frac{1}{2}$

Option 4: $\sqrt{3}$

Team Careers360 23rd Jan, 2024

Correct Answer: $\frac{1}{4}$


Solution : We have,
$\cos \theta = \frac{\sqrt{3}}{2}$
⇒ $\cos \theta = \cos 30^\circ$
⇒ $\theta = 30^\circ$
Now,
$\tan^2 \theta \cos^2 \theta=\tan^2 30^\circ \cos^2 30^\circ=
(\frac{1}{\sqrt3})^2 ×(\frac{\sqrt{3}}{2})^2$
$= \frac{1}{4}$
Hence, the correct answer is $\frac{1}{4}$.

Question : A man can cover a certain distance in 3 hours and 36 minutes if he walks at a rate of 5 km/h. If he covers the same distance on a bicycle at a rate of 24 km/h, then the time taken by him in minutes is:

Option 1: 40

Option 2: 45

Option 3: 50

Option 4: 55

Team Careers360 25th Jan, 2024

Correct Answer: 45


Solution : Let the time taken by him on a bicycle be $x$ hour.
Distance covered by him by walking = $5×3\frac{36}{60}=5×\frac{18}{5}=18$ km.
Distance covered by him on the bicycle = 24$x$ km.
According to the question,
24$x$ = 18
⇒ $x = \frac{18}{24}$ hour = $\frac{18}{24}×60$

Question : Shiva’s monthly salary is Rs.75,000. He spends Rs.12,000 on household items, Rs.14,000 on LIC and mutual funds, Rs.15,000 on his children’s education, and keeps Rs.10,000 for miscellaneous expenses. His savings are Rs.21,000 per month and he donates the rest of the amount to an orphanage. The percentage of his income that he donates is:

Option 1: 3%

Option 2: 6%

Option 3: 8%

Option 4: 4%

Team Careers360 24th Jan, 2024

Correct Answer: 4%


Solution : Percentage Donated = $\frac{\text{Amount Donated}}{\text{Total Income}}\times 100$
First, let's calculate the total expenses:
Total Expenses = Household items + LIC and mutual funds + Children's education + Miscellaneous expenses Total Expenses
= Rs. 12,000 + Rs. 14,000 + Rs. 15,000 + Rs. 10,000 = Rs.
