About 11% of the patients who got admitted to the hospital on that particular day were of age:

Option 1: either between 35 years and 40 years or between 55 years and 60 years

Option 2: between 60 years and 65 years

Option 3: between 35 years and 40 years

Option 4: between 35 years and 40 years and between 55 years and 60 years

Team Careers360 26th Jan, 2024

Correct Answer: between 35 years and 40 years and between 55 years and 60 years


Solution : Total patients = 35
From the given graph,
About 11% of the patients were admitted.
⇒ 11% of 35 $=\frac{11}{100} \times 35=3.85 \approx 4$
Here, The number of patients between 35 and 40 years is 4.
Also, The number of patients between 55 and 60 years is 4.
Hence, the correct answer is between 35 and 40 years and between 55 and 60 years.

Question : Select the option that expresses the given sentence in passive voice.

A sudden noise frightened the horse.

Option 1: The horse has been frightened by a sudden noise.

Option 2: The horse was frightened by a sudden noise.

Option 3: The horse had frightened by a sudden noise.

Option 4: The horse got frightened by a sudden noise.

Team Careers360 26th Jan, 2024

Correct Answer: The horse was frightened by a sudden noise.


Solution : The second option is the correct choice.

Passive voice is the voice in which the object experiences an action rather than the person who performs the action. Hence, the object in the active sentence becomes the subject in the passive voice.

The structure of the passive sentence in the simple past tense is: Singular object + was + past participle form of the verb + by followed by the agent of the action.

Therefore, the correct sentence is: The horse was frightened by a sudden noise.

Question : If $p^2+\frac{1}{p^2}=14$, then find the value of $\left(p^3+\frac{1}{p^3}\right)$.

Option 1: 56

Option 2: 60

Option 3: 48

Option 4: 52

Team Careers360 26th Jan, 2024

Correct Answer: 52


Solution : Given: $p^2+\frac{1}{p^2}=14$
we know that,
$p^2+\frac{1}{p^2}=(p+\frac{1}{p})^2-2\times p\times \frac{1}{p}$
$⇒(p+\frac{1}{p})^2-2\times p\times \frac{1}{p}=14$
$⇒(p+\frac{1}{p})^2=14+2$
$⇒(p+\frac{1}{p})^2=16$
$⇒(p+\frac{1}{p})=4$
Now cubing both sides, we get:
$⇒(p+\frac{1}{p})^3=4^3$
$⇒p^3+\frac{1}{p^3}+3\times p\times \frac{1}{p}(p+ \frac{1}{p})=4^3$
​​​​​​​​​​​​​​$⇒​​​​​​​p^3+\frac{1}{p^3}+3\times4=64$
​​​​​​​$⇒​​​​​​​p^3+\frac{1}{p^3}=64-12$
​​​​​​​$⇒​​​​​​​p^3+\frac{1}{p^3}=52$
​​​​​​​Hence, the correct answer is 52.

Question : Directions: Select the letter cluster from the given options that can replace the question mark (?) in the following series.
DPMW, EOLX, FNKY, ?

Option 1: DEWX

Option 2: EMJX

Option 3: GOKY

Option 4: GMJZ

Team Careers360 26th Jan, 2024

Correct Answer: GMJZ


Solution : Given:
DPMW, EOLX, FNKY, ?

In the above-given letter clusters, add 1 to the place value of the first and fourth letters and subtract 1 from the place value of the second and third letters of the previous term to obtain the next term in the series.
DPMW→D + 1 = E; P – 1 = O; M – 1 = L; W + 1 = X→EOLX
EOLX→E + 1 = F; O – 1 = N; L – 1 = K; X + 1 = Y→FNKY
FNKY→F + 1 = G; N – 1 = M; K – 1 = J; Y + 1 = Z→GMJZ

So, GMJZ is the missing term in the series. Hence, the fourth option is correct.

Question : Directions: In the following question, find the odd number from the given alternatives.

Option 1: 125

Option 2: 512

Option 3: 1321

Option 4: 1728

Team Careers360 27th Jan, 2024

Correct Answer: 1321


Solution : Let's check the options –
First option: 125→(5)3 = 125
Second option: 512→(8)3 = 512 
Third option: 1321→1321 is not a cube of any number.
Fourth option: 1728→(12)3 = 1728

So, the third option does not follow a similar pattern as the other three options. Hence, the third option is correct.

Question : If A = 60°, B = 30°, then find the value of sin A cos B + cos A sin B.

Option 1: 0

Option 2: 12

Option 3: 13

Option 4: 1

Team Careers360 26th Jan, 2024

Correct Answer: 1


Solution : Given that A = 60°, B = 30°
sin A cos B + cos A sin B
= sin (A + B)
= sin (60° + 30°)
= sin 90°
= 1
Hence, the correct answer is 1.

Question : Select the most appropriate option that can substitute the underlined segment in the following sentence.

I need to put out my clothes before I leave for work this morning; otherwise, I will be restless when I return.

Option 1: need for put out

Option 2: need to put in

Option 3: need to put off

Option 4: need to put away

Team Careers360 27th Jan, 2024

Correct Answer: need to put away


Solution : The most appropriate option is the fourth option.

Explanation: Put away means to tidy up or store something in its designated place. In the context of the sentence, putting away the clothes implies organising them neatly before leaving for work, ensuring they're in their proper place, which would prevent feeling restless upon return due to a messy environment.

The meanings of the other options are as follows:

  • Put out: It generally means extinguishing something (like putting out a fire) or displaying something (like putting out a display).
  • Put in: This means adding something to a place or situation.
  • Put off: It means to postpone or delay.

Therefore, the correct sentence would be, "I need to put away my clothes before I leave for work this morning; otherwise, I will be restless when I return".

Question : Fill in the blank with an appropriate option.
Earwax is a helpful and ______ part of your body's defenses.

Option 1: transparent

Option 2: flowing

Option 3: tedious

Option 4: natural

Team Careers360 27th Jan, 2024

Correct Answer: natural


Solution : The correct choice is the fourth option.

Natural denotes not being made or caused by human beings. It fits well in the context of this sentence because earwax is a natural product of the human body.

The meanings of the other words are:

  • Transparent: It means that you can see through.
  • Flowing: It denotes moving in a smooth and continuous way (like water).
  • Tedious: It denotes boring and tiring.

Therefore, the correct answer is natural.

Question : Directions: Arrange the following words as per their order in a dictionary.
1. Absolute
2. Abrasive
3. Absorption
4. Abundance
5. Abiogenesis

Option 1: 5, 2, 3, 1, 4

Option 2: 2, 5, 1, 3, 4

Option 3: 5, 2, 1, 3, 4

Option 4: 3, 4, 5, 2, 1

Team Careers360 26th Jan, 2024

Correct Answer: 5, 2, 1, 3, 4


Solution : Given:
1. Absolute 2. Abrasive 3. Absorption 4. Abundance 5. Abiogenesis

Step 1: Compare the first letter of each word. Since all the words start with the same letter A, then move on to the next letter.
Step 2: The second letter of each word is the same, i.e., b, then move on to the next letter.
Step 3: Compare the third letter of (Absolute, Abrasive, Absorption, Abundance, Abiogenesis). Abiogenesis will come first as i comes before sr, and u in alphabetical order. Similarly, Abrasive will come before Absolute, Absorption, and Abundance as r comes before s and u in alphabetical order. Also, (Absolute, Absorption) will come before Abundance as s comes before u in alphabetical order.
Step 4: The fourth letter of (Absolute, Absorption) is the same, so move on to the next letter.
Step 5: Compare the fifth letter of (Absolute, Absorption). Absolute will come before Absorption as l comes before r in alphabetical order.

So, the sequence is Abiogenesis, Abrasive, Absolute, Absorption, Abundance, or 5, 2, 1, 3, 4. Hence, the third option is correct.
