It costs Rs. 10 a kilometer to fly and Rs. 2 a kilometer to drive. If one travels 200 km covering x km of the distance by flying and the rest by driving, then the cost of the trip is

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 5

Total distance travelled = 200 km
Total distance travelled by Flying = x km
Total distance travelled by driving = 200 - x
Total cost of this trip 
= (x) × 10 + (200 - x) × 2
= 10x + 400 - 2x
= 8x + 400

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 6

If 6 men working 8 hours a day earn Rs. 1680 per week, then 9 men working 6 hours a day will earn per week:

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 6

Total hours of work done in a week = 6 × 8 × 7 = 336 hrs

Money earned by working 1 hr = 1680/336 = Rs. 5

Total money earned by 9 men working 6 hours a day = 5 × (9 × 6 × 7) = Rs. 1890

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 7

Directions: Anjali obtained a total of 500 marks in her examination. The given pie-chart shows the percentage distribution of her marks in various subjects. The maximum marks of each subject are 100. Study the pie-chart and answer the questions that follow.

Q. In order to get 75% marks in English, how many more marks did she require?

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 7

Total marks secured = 500
Marks secured in English = 14% of 500 = 70
∵ Maximum marks of each subject = 100
Marks required to get 75% = 75% of 100 = 75
∴ More marks required = 75 – 70 = 5

Two taps A and B fill a tank in 24 minutes and 32 minutes respectively. If both the taps are opened simultaneously, after how many minutes tap B should be closed so that the tank fills up in 18 minutes.

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 9

Tap A fills 1/24 of the tank in 1 minute
Tap B fills 1/32 of the tank in 1 minute 

Let,
After x minutes tap B should be closed

so,
⇒ 18/24 + x/32 = 1
⇒ x/32 = 1 - 18/24
x = 6/24 × 32 = 8minutes

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 10

At a telephone exchange, three phones ring at intervals of 20 sec, 24 sec and 30 seconds - If they ring together at 11:25 am, when will they next ring together?

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 10

Time taken by three phones to ring together = LCM of 20, 24 and 30

⇒ Time taken by three phones to ring together = 120 seconds
(∵ 1 min = 60 seconds)

⇒ Time taken by three phones to ring together = 120/60 = 2 min

If the three phones ring together at 11:25 am then they will next ring together after 2 minutes i.e. at 11:27 am.
∴ Time at which the phones next ring together = 11:27 am

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 11

The length of one side of a rhombus is 41 cm and its area is 720 cm2. What is the sum of the lengths of its diagonals?

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 11

Area of Rhombus = 1/2 × product of diagonals
⇒ 720 = 1/2 × product of diagonals
⇒ Product of diagonals = 1440
(Side of rhombus)= (half of one diagonal)2 + (half of the other diagonal)2
⇒ (One diagonal)2 + (Other diagonal)2 = 41 × 41 × 4
(Sum of two diagonal)2 = (One diagonal)2 + (other diagonal)2 + 2 × product of diagonals
⇒ (Sum of two diagonal)2 = 6724 + 2880 = 9604
∴ Sum of two diagonal = 98cm

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 12

A boat goes upstream at speed of 10 km/hr. It goes downstream at a speed of 30 km/hr. how much time will the boat take to cover a distance of 30 km in still water?

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 12

Let the speed of boat in still water be x
Let the speed of the stream be y
⇒ Upstream speed = x - y = 10 km/hr
⇒ Downstream speed = x + y = 30 km/hr
Solving
⇒ x = 20 Km/hr
⇒ y = 10 km/hr
⇒ Speed of boat in still water = 20 km/hr
∴ Time = Distance ÷ Speed = 30 ÷ 20 = 1.5 hours = 90 minutes

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 13

The simple interest on a certain sum at 12% per annum for 3 years is Rs. 4,140. What is the compound interest on the same sum at 8% for two years?

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 13

Let the amount invested be x,
Simple interest earned on it = (x × 12 × 3) /100 = 4140
⇒ x = (4140 × 100) / (12 × 3)
⇒ x = 11500
Compound interest earned on it for 2 years at 8% = 11500(1 + 8/100)2 – 11500
⇒ CI = 11500(1.08)2 – 11500
∴ CI = Rs. 1,913.60

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 14

The monthly income of Kamal and Kobita are in the ratio of 10 ∶ 7 and their ratio of their savings is 5 ∶ 2. If each of them expend Rs. 500 in the month, the monthly income of Kamal is -

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 14

The monthly income ratio of Kamal and Kobita are in the ratio,
⇒ 10 ∶ 7
Their Savings ratio = 5 ∶ 2
Let Kamal’s monthly income be Rs. 10x
Kobita’s monthly income = Rs. 7x
Kamal’s monthly savings = Rs. 5y
Kobita’s monthly savings = Rs. 2y
According to the problem,
⇒ 10x - 5y = 500      ----(1)
According to problem,
⇒ 7x - 2y = 500      ----(2)
From (2) - (1) we get,
⇒ 3x = 300
⇒ x = 100
∴ Monthly income of Kamal = 10 × 100 = Rs. 1000

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 15

A question paper comprises of 150 questions out of which 60 questions are of technical field. From the remaining questions, 40% are from English, 40% are from reasoning and the remaining from GK. If 80% of the technical, 50% of the English, 50% of the reasoning and 50% of the GK questions are compulsory, what percentage of the total questions is compulsory to attempt?

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 15

No. of technical questions = 60
No. of English questions = 40% of (150 – 60) = 0.4 × 90 = 36
No. of reasoning questions = 40% of (150 – 60) = 0.4 × 90 = 36
No. of GK questions = 150 – 60 – 36 – 36 = 18
Compulsory technical questions = 0.8 × 60 = 48
Compulsory English questions = 0.5 × 36 = 18
Compulsory reasoning questions = 0.5 × 36 = 18
Compulsory GK questions = 0.5 × 18 = 9
Total compulsory questions = 48 + 18 + 18 + 9 = 93
∴ Required percentage = (93/150) × 100 = 62%

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 17

Read the passage and answer the following questions.

Care should be taken when submitting manuscripts to book publishers. A suitable publisher should be chosen, by a study of his list of publications or an examination in the bookshops of the type of books in which he specializes. It is a waste of time and money to send the typescript of a novel to a publisher who publishes no fiction, or poetry to one who publishes no verse, though all too often this is done.

A preliminary letter is appreciated by most publishers, and this should outline the nature and extent of the typescript and enquire whether the publisher would be prepared to read it (writers have been known to send out such letters of inquiry in duplicated form, an approach not calculated to stimulate a publisher’s interest).

It is desirable to enclose the cost of return postage when submitting the typescript and finally it must be understood that although every reasonable care is taken of material in the Publishers’ possession, responsibility cannot be accepted for any loss or damage thereto.

Authors are strongly advised not to pay for the publication of their work. If an MS is worth publishing, a reputable publisher will undertake its publication at his own expense, except possibly for works of an academic nature. In this connection, attention is called to the paragraphs on Self-publishing and vanity publishing, at the end of this section.

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 19

Read the passage and answer the following questions.

Care should be taken when submitting manuscripts to book publishers. A suitable publisher should be chosen, by a study of his list of publications or an examination in the bookshops of the type of books in which he specializes. It is a waste of time and money to send the typescript of a novel to a publisher who publishes no fiction, or poetry to one who publishes no verse, though all too often this is done.

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 19

Option 1. As precautions to be taken by authors most aptly describes the content of the passage, it should be the most suitable title for the passage so option 1 is correct.

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 20

Tarun exclaimed that the food was great.

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 20

In the direct speech, the quotes must be used and the tense needs to be changed as well. The sentence mentions the word 'the' and not 'that' thus 'this' would be incorrect here. The correct tense here is simple present as the tense in indirect speech is simple past. Option 2 is the correct answer.

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 21

In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'.

Q. Kartik said to Hari, “These glasses (1) / suits you and you are (2) / looking smart in it” (3) / No error (4)

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 21

The error is in part 2 of the sentence, “suit” must be used instead of “suits”.
Singular subjects need singular verbs (adding ‘s’ to the verb).
Plural subjects need plural verbs (not adding ‘s’ to the verb).

For example,
‘Dogs bark’.
‘The earth spins’.

‘These’ is a plural form. Thus, we should use the plural verb (without ‘s’).
Hence option 2 is the correct answer. 

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 22

Fill in the blanks.

Q. Though Emma hailed from Spain, she spoke _____English.

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 22

The correct answer is impeccable
Let us look at the meaning of the other words

Sinful: immoral
Impeccable: High standard

Imperfect: Not perfect / faulty / incomplete

Influent: not speaking fluently
Here, though Emma hailed from Spain she is good at English. Thus, ‘Impeccable’ is the most suited word.

For example,
‘She had impeccable taste in clothes’.
‘He was dressed in a suit and an impeccable white shirt’.
Hence the correct answer is option 2.

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 23

Gina told Chelsea that she’d rather die than move to a small town like Sedona. 

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 23

When changing the sentence to direct speech, the pronoun ‘she’d’ in the 2nd person changes to ‘I’d’ in the first person. The conjunction ‘that’ is no longer necessary. The verb ‘told’ in the simple past tense is replaced by the verb ‘said’ in the simple past tense. The name– ‘Chelsea’ is inside the inverted the commas as she is the listener and the name – ‘Gina’– stays outside as she is the speaker.

Thus, the sentence will be,
Added name inside the inverted comma “Chelsea, + changed pronoun ‘I’d’ + rather die than move to a small town like Sedona.” + speaker name ‘Gina’ + changed verb ‘said’.

Thus, the correct answer is option 2.

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 24

In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'.

Q. Barack Hussein Obama served as (1) / the 44th president of the United States of America (2) / since 2009 to 2017. (3) / No error (4)

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 28

The error is in part 3 of the sentence, “from” must be used instead of “since”

Since is used to express the time and to mean ‘because’. Since means “from a time in the past until the present”. “Since” should not be used with “to”. Instead, use “from” and “to” or “from” and “until”.
Hence option 3 is the correct answer. 

AIIMS CRE Data Entry Operator Mock Test- 3 - Question 29

Read the passage and answer the questions that follow. A word has been highlighted in the passage for your attention.

Marie was born in 1867 in Warsaw, Poland, where her father was a Professor of Physics. At an early age, she displayed a brilliant mind and a blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women. Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French university, where she earned her master's degree and a doctorate in physics.

Marie was fortunate to have studied at the Sorbonne with some of the greatest scientists of her day, one of whom was Pierre Curie. Marie and Pierre were married in 1895 and spent many productive years working together in the physics laboratory. A short time after they discovered radium, Pierre was killed by a horse-drawn wagon in 1906. Marie was stunned by this horrible misfortune and endured heartbreaking anguish. Despondently she recalled their close relationship and the joy that they had shared in scientific research. The fact that she had two young daughters to raise by herself greatly increased her distress.

Curie's feeling of desolation finally began to fade when she was asked to succeed her husband as a physics professor at the Sorbonne. She was the first woman to be given a professorship at the world-famous university. In 1911 she received the Nobel Prize in chemistry for isolating radium. Although Marie Curie eventually suffered a fatal illness from her long exposure to radium, she never became disillusioned about her work. Regardless of the consequences, she had dedicated herself to science and to revealing the mysteries of the physical world.

Q. Which of the following words reflect the personality of Marie?

Detailed Solution for AIIMS CRE Data Entry Operator Mock Test- 3 - Question 29

Option 4 is the correct answer.
It is mentioned in the following line of the passage: At an early age, she displayed a brilliant mind and a blithe personality.

The correct answer is feeble.
Let us look at the meaning of the other words
Easy: Achieved without great effort
Tough: strong enough to withstand adverse conditions

Feeble: weak
Strong: Powerful

As old people are weak, Feeble is the most suited here

For example,
‘Rita’s grandmother is quite feeble and needs help with her daily activities’.
Hence option 3 is the correct answer.
