AIIMS CRE Data Entry Operator Mock Test- 1 - NEET MCQ

Hence, the correct option is (c)

• Neutrophils and lymphocytes orginate from the bone marrow.

• B-lymphocytes, which originate in the bone marrow, produce antibodies to fight off infection. The antibody attaches to the microbe, tagging it as "foreign.” Infection-fighting cells called neutrophils can now recognize the microbe, engulf and digest it.

The CISF is a Central Armed Police Force that secures critical infrastructure, including airports and nuclear installations. Its establishment aimed to protect sensitive public sector undertakings, and it has since expanded its role to include securing various important facilities across the nation.

Hence the correct answer is option C.

⇒(3)²²×(5)⁷×(7)⁵×(3)²×(17)²

Total no. of prime factors, n= Sum of powers ∴n=22+7+5+2+2

∴ n = 38

(-A)² = 4 * 16 * 25

A = 40

Bx² + Ax + 4 = 0 has real and equal roots

(A)² = 4 * B * 4

(40)² = 4 * B * 4

B = 100

√B = √100

√B = 10

If the two files have the same name and are of the same file type then the files cannot be saved in the same folder but they can be stored in a different folder with the same name and file type.

⇒ Downstream speed = 7 km/h
⇒ Speed of stream = 3 km/h
Speed of stream = 1/2 (Downstream speed – Upstream speed)
⇒ 3 = ½ (7 – Upstream speed)
⇒ Upstream speed = 7 – 6 = 1 km/h
∴ Time taken during upstream = 14/1 = 14 hours

Speed of train = 45 km/hr = 45 × (5/18) = 12.5 m/sec
Distance to cover = 150 + 180 = 330 m
∴ Time taken by train to cross the platform = 330/12.5 = 26.4 sec

n/p ratio of Sodium = (23 – 11)/11 = 12/11 = 1.09
n/p ratio of Potassium = (39 – 19)/19 = 20/19 = 1.05
∴ Required difference = 1.09 – 1.05 = 0.04

Let cost price of an article be Rs. 1.
C.P of 6 articles = Rs. 6
Selling price of 8 articles = Rs. 6
Cost price of 8 article = Rs. 8
Loss percentage
= [(8 - 6)/8] × 100
= (2/8) × 100
= 25%
∴ Loss percentage is 25%.

BC = 25 m
AB = BC tan 60° = 25√3 m
AC = BC sec 60° = 50 m
Total tree length = AB + AC
⇒ 43.30 + 50 = 93.30

Let the length of train B be ‘x’ m
⇒ Length of train A = (x + 46) m

Now, when two bodies are moving towards each other or in opposite direction, their relative speed is the sum of their individual speeds
⇒ Relative speed of trains = 97 + 83 = 180 km/hr. = 180 × (5/18) = 50 m/sec.

Now,
⇒ Time taken by trains to cross each other = Sum of lengths of train/relative speed
⇒ 5.4 = (x + 46 + x)/50
⇒ 270 = 2x + 46
⇒ 2x = 224
⇒ x = 224/2 = 112 m
∴ Length of train B is 112 m

Two successive increase of 30% = 30 + 30 + (30 × 30)/100 = 69%
Two successive decrease of 30% = 30 + 30 – (30 × 30)/100 = 51%
∴ Required ratio = 69 : 51

Length of two parallel sides of trapezium = 50 cm and 30 cm
Let the height be x cm
According to problem,

⇒ 40x = 160
⇒ x = 4
∴ Height = 4 cm

In Direct speech, the message is conveyed on the words of the author or concerned person.

In Indirect speech, the message in conveyed in our words.

When we convert indirect speech to direct speech we add inverted commas. 

Some notable changes that were made during this conversion were - the exclamation point was added

Both the subject switch places

A comma is added after 'Julia'

So, the correct answer would be -

“Julia, you are spending too much time in the hot tub!” Richard yelled.

Thus, option 2 is the correct option. 

The word 'absolve' means 'pardon;forgive.' Option 3 is the correct answer. 

The second option is the right answer. Adapted means being accustomed or habituated with something that it no longer has drastic impact on us and this fits in well in the given blank. Accused means to blame, appreciative means to acknowledge someone or something and aroused means being physically affected; these meanings do not fit in the given blank.

Hence, adapted is the most appropriate word for blank E.

Option 1 is eliminated as 'listening' must be followed with the preposition 'to' which is not present here. Option 3 is incorrect as 'famous' cannot fit in the second blank. The word here has to be a verb. Option 4 does not convey a logical meaning. Option 2 conveys a proper meaning. The man listened to folk tales of places and used them for composing his songs.

The idiom 'cash in the chips' means 'sell something.'
Eg: He cashed in the chips and went on a world tour.
Option 1 is the correct answer.

The fourth option is the right answer. Completely and absolutely refer to something that is in its entirety and this meaning does not fit in the blank. Accordingly means depending on certain specific situations and this again, does not hold the exact meaning for the given blank. Optimally means something to its fullest potential and this meaning holds the most appropriate understanding for the given blank.

Thus, optimally is the most appropriate word for blank C.

Correct answer- Option 2
The first phrase is c which provides a basic situation for the sentence to start from, the second phrase d builds up on the given context, the third phrase b continues ahead the build and the fourth phrase a connects the entire sentence coherently together. Thus, the correct sequence is- CDBA.

Corrected sentence:
The music blared from the boom box and the proud mother watched her daughter performing her first gig as a disk jockey.

The word 'abortive' means 'unproductive;vain.' Option 4 is thus the correct answer.

The error lies in part 2 of the sentence as the preposition 'with' cannot be used with the verb 'impart' and it must be eliminated. 'Impart' means 'convey something.' It should read as: ' They also impart him  priceless knowledge about..' 

The error lies in part B.
The sentence uses the incorrect form ‘verified'.

Since the sentence uses the preposition 'of' with the above-given word, it cannot be in its verb form 'verfied'. As it is used with a preposition, it should be in its noun form 'verification'.
Therefore, the correct answer is option 2.

The sentence uses the form can be, which is incorrect and needs improvement.

The sentence uses the conditional conjunction 'if you had', showing that the second sentence is dependent on the conditional existence of the first.

The second sentence, then, must contain a verb that shows this conditional future outcome, if the thing given by the first sentence occurs.

This can only be given by a modal verb.

Should shows a duty, and shall shows a future tense which do not fit the context.

Only modal verb 'would' reflects the conditional future possibility. 

The only alternative that improves the sentence is Would have.

None of the other alternatives can make the sentence meaningful.
Therefore, the correct answer is option 3.

The rule when converting direct speech to indirect is to pay attention to each word and change it accordingly. Whenever there is a question in the sentence, the verb 'said' becomes 'asked' in reported speech.

In case of non wh-questions such as 'have you? or 'will you', which indicate a possibility of something happening, the conditional nature is shown by using 'if' after 'asked'.

The sentence contains the future tense verb 'will', which, in reported speech becomes 'would'.
Therefore, the correct answer is option 2.

The part Q talks about 'the great cultural movement', which must be associated with some specific movement, as shown by the use of article 'the'.

Now, the part P talks about something known as 'Enlightenment'. So, they must be connected.
So, QP is the correct order.

This order is only reflected by option 3, which gives the order RQPS.
Therefore, the correct answer is option 3.

From the given options “for” is correct answer as it makes grammatical sense in the context of the statement.

The error lies in part C.
The sentence uses the incorrect form ‘letter'.

The sentence uses the word to refer to a 'non-striker' which is the second thing of the two things mentioned in the previous part (first is the 'bowler').

When the sentence refers to two things at the same time, adjectives such as 'former' (first one) and 'latter' (the second one) are used.

Given the context, the correct word here should be 'latter' which basically means something which comes after something.
Therefore, the correct answer is option 3.
