LIC ADO Memory Based Paper (6th July 2019) (Previous Year Paper)

The correct answer is Surface-wave based systems​.

Key Points

It is mentioned in the passage - Ultrasound surface wave acoustic touchscreens are often used in the medical field, casinos, amusement facilities, public facilities, and financial institutions.

Option 2, option 3, option 4, and 5 have to be eliminated as the passage specifically mentions the use of Surface-wave based systems which is the Ultrasound surface wave acoustic touchscreens

Thus, Option 1 is the most suitable option here out of the given options.

The correct answer is ​Ultrasound surface wave acoustic touchscreens are often used in the medical field, casinos, amusement facilities, public facilities, and financial institutions.

Key Points

It is mentioned in the passage - Because ultrasound surface wave acoustic touchscreens use glass, they have high transmittance and long operating lives. Ultrasound surface wave acoustic touchscreens are often used in the medical field, casinos, amusement facilities, public facilities, and financial institutions.

• Option 1 is incorrect as 'the change in the electrical field is noted and the coordinates of the point of contact are calculated by the processor' not the piezoelectric receivers.
• Option 2 is incorrect as resistive touchscreens offer 75 percent clarity as per the passage.
• Option 3 is incorrect as SAW touchscreens can read touch commands created with a traditional stylus as mentioned in the passage.
• Option 4 is incorrect as the passage mentions mobile phones may use two types of input devices
• Option 5 enlists the usage of ultrasound surface wave acoustic touchscreens which is mentioned in the latter half of the first paragraph.

Thus, the statement only in Option 5 is true as per the passage.

The correct answer is a normal glass panel that is covered with conductive and resistive metallic layers​.

Key Points

It is mentioned in the passage- The resistive system consists of a normal glass panel that is covered with conductive and resistive metallic layers.

Option 1, option 2, option 4, and 5 have to be eliminated as the passage specifically defines the composition of the resistive system in paragraph 1.

While answering questions that start with 'According to the passage', we have to strictly adhere to the information given in the passage and answer accordingly.

The correct answer is Transmit.

Key Points

• Relays means receive and pass on (information or a message). It is a verb.
• Transmits means to cause (something) to pass on from one person or place to another; circulate; pass on. It is a verb.
• Thus the word most similar to the word relays is transmit.

Additional Information

Let's look at the meaning of the other words:

The correct answer is Impede.

Key Points

• Disrupt means interrupt (an event, activity, or process) by causing a disturbance or problem. It is a verb.
• Impede means to delay or prevent (someone or something) by obstructing them; hinder. It is a verb.
• Thus the word most similar to the word disrupt is impede.

Additional Information

Let's look at the meaning of the other words:

The correct answer is Untouchable.

Key Points

• Tactile means of or connected with the sense of touch. It is an adjective.
• Untouchable means not able or allowed to be touched or affected. It is an adjective.
• Thus the word most opposite to the word tactile is untouchable.

Additional Information

Let's look at the meaning of the other words:

The correct answer is SAW touch screen lasts longer than a capacitive touch screen.​

Key Points

The statement mentioned in option 4 is not supported by the second and third paragraphs as the comparison mentioned in the second paragraph is between capacitive and resistive touchscreen whereas the third paragraph only mentions that SAW touchscreens can last for hundreds of thousands of touches, it does not explicitly or implicitly mentions which touchscreen out of the two lasts longer.

Option 1 is supported by the second and third paragraphs as it is mentioned in the passage- ''Resistive touch screen panels are generally more affordable but offer only 75 percent clarity and the layer can be damaged by sharp objects. One advantage of the capacitive system over the resistive system is that it transmits almost 92 percent of the light emitted from the monitor, whereas the resistive system transmits only about 75 percent.''

Option 2 is supported by the second and third paragraphs as it is mentioned in the passage- ''One advantage of the capacitive system over the resistive system is that it transmits almost 92 percent of the light emitted from the monitor, whereas the resistive system transmits only about 75 percent.''

Option 3 is supported by the second and third paragraphs as it is mentioned in the passage- ''This is because performing touch commands on a SAW touchscreen places little or no stress on its components. Therefore, SAW touchscreens can last for hundreds of thousands of touches.''

Option 5 is supported by the second and third paragraphs as it is mentioned in the passage- ''In fact, you can use any object to perform touch commands on a SAW touchscreen. Any object placed on the display surface will disrupt the sound waves in that area''. 

Thus, Option 4 is the correct option which cannot be inferred from the paragraphs mentioned and is not supported by the second and third paragraphs.

The correct answer is The picture quality of the capacitive touch screen is much better than that of the resistive touch screen.

Key Points

It is mentioned in the passage- One advantage of the capacitive system over the resistive system is that it transmits almost 92 percent of the light emitted from the monitor, whereas the resistive system transmits only about 75 percent. This gives the capacitive system a much clearer picture than the resistive system.

Option 1, option 4, and option 5 are incorrect as they are outside the scope of the passage and cannot be inferred properly.

Option 2 is incorrect as it is not explicitly mentioned that Financial institutions only use Surface wave acoustic (SAW) touchscreens.

Thus, Option 3 is the most suitable option here which can be properly inferred from the passage.

The correct answer is An electrical current runs through the two layers while the monitor is dysfunctional. ​

Key Points

It is mentioned in the passage- An electrical current runs through the two layers while the monitor is operational. When a user touches the screen, the two layers make contact exactly at that spot. The change in the electrical field is noted and the coordinates of the point of contact are calculated by the processor. 

Here option 3 mentions monitor as dysfunctional which is false as per the passage.

All the other options are true and are in the context of the passage.

The correct answer is Mobile touchscreen technology.

Key Points

• Option 1 is the most suitable title for the passage here as it encapsulates the gist of the entire passage.
• Option 2 is incorrect as the passage describes all the touch technologies which are used in mobile phones. Here capacitive touch screen is one of the technologies mentioned. Also, its evolution is nowhere discussed in the passage.
• Option 3 is incorrect as the passage describes more than just the advantages of a touch screen.
• Option 4 and 5 are incorrect as the passage is specifically regarding mobile touchscreen technology.

Thus, Option 1 is the most suitable option out of the given options.

The correct answer is screaming at the top of his voice.

Key Points

The underlined phrase 'Scream at the top of his voice' is grammatically incorrect. The verb 'scream' should be replaced with 'screaming' to make the sentence grammatically correct.

At the top of one's voice: If you say something at the top of your voice, you say it as loudly as possible. For e.g. 'Damn!' he yelled at the top of his voice.

Therefore, option 3) is the correct answer.

Thus, the correct sentence is: Screaming at the top of his voice, Richard told his neighbour not to make a din after 11 pm.

Additional Information

A gerund is a verbal that ends in -ing and functions as a noun. The term verbal indicates that a gerund, like the other two kinds of verbals, is based on a verb and therefore expresses action or a state of being. However, since a gerund functions as a noun, it occupies some positions in a sentence that a noun ordinarily would, for example: subject, direct object, subject complement, and object of a preposition.

For e.g. Traveling might satisfy your desire for new experiences. (Traveling is the gerund.)

The correct answer is 'oil tanks stretched across the sky'.

Key Points

• The preposition 'across' is used to express 'in every part of a place, group of people, etc.'
• Examples, 
• Her family is scattered across the country.
• This view is common across all sections of the community.
• The given sentence means that the smoke was spread everywhere in the sky.
• So, 'across' is the most suitable preposition to be used in the given sentence.
• Therefore, option 4 is the correct answer.

The correct answer is Less than 2 hours is left

Key Points

• In the given sentence, the phrase '2 hours are left' is incorrect.
• When using adjectives like much, less, little and more are used, they are followed by the verb in the singular format. 
• ​In the current scenario, the 'less than 2 hours' refers to a specific time period that will be treated as one and thus is singular.
• Hence, the 'are left' in the sentence will be replaced with 'is left' to make the sentence grammatically correct.

The correct sentence will be: Less than 2 hours is left before the bomb explodes and annihilates the city and its inhabitants. 

Thus, the correct answer is Less than 2 hours is left

Additional Information

Let's look at the meanings of some of the hard words:

The correct answer is Lest he should get.

Key Points

• In the given sentence, the phrase 'lest he should not get' is incorrect.
• The sentence means that Aaron was warned against using painkillers because he might get addicted to them.
• 'Lest' is a conjunction that means 'to avoid the risk of'. 
• It includes the implication of 'not' within the conjunction itself and thus the 'not' in the sentence is redundant.
• Hence, the 'lest he should not get' needs to be replaced with 'lest he should get'.

The correct sentence is: Aaron is warned against strong pain killers lest he should get addicted.

The correct answer is Option (2) i.e. look for

Key Points

• Look out (Phrasal Verb): be vigilant and take notice.
• Look after (Phrasal Verb): take care of
• Look forward to (Phrasal Verb): await eagerly
• Look for (Phrasal Verb): to hope to get something that you want or need.
• The sentence implies that the person (subject) is in search of the circumstances they want. Therefore, the only phrasal verb that goes well with the context of the sentence is 'look for'.
• Hence, option 2 is correct.

Correct sentence: The people who get on in this world are the people who get up and look for the circumstances they want, and if they cannot find them, make them.

Additional Information

Some other phrasal verbs with the verb 'look'

• Look ahead: to think about and plan the future.
• Look away: to turn your eyes away from someone or something that you were looking at
• Look back: to think about something that happened in the past
• Look down on: to think something or someone is inferior

Calculation:

The series follows the following pattern:

⇒ 8 + 12 = 20

⇒ 20 + 16 = 36

⇒ 36 + 20 = 56

⇒ 56 + 24 = 80

⇒ 80 + 28 = 108

∴ The value of ? is 108

Given:

7, 14, 42, 168, 840, ?

Calculation:

The series follows the following pattern:

7 × 2 = 14

14 × 3 = 42

42 × 4 = 168

168 × 5 = 840

840 × 6 = 5040

Given:

27, 32, 42, 57, 77, ?

Calculation:

The series follows the following pattern:

27 + (5 × 1) = 32

32 + (5 × 2) = 42

42 + (5 × 3) = 57

57 + (5 × 4) = 77

77 + (5 × 5) = 102

Given:

5, 3, 3, 5, 15, ?

Calculation:

The series follows the following pattern:

5 × 1 - 2 = 3

3 × 2 - 3 = 3

3 × 3 - 4 = 5

5 × 4 - 5 = 15

15 × 5 - 6 = 69

∴ 69 will come in place of the question mark ('?').

GIVEN:

640, 322,164, 86, 48, ?

Calculation:

The series follows the following pattern:

⇒ 640 ÷ 2 + 2 = 322

⇒ 322 ÷ 2 + 3 = 164

⇒ 164 ÷ 2 + 4 = 86

⇒ 86 ÷ 2 + 5 = 48

⇒ 48 ÷ 2 + 6 = 30

∴ The required value of "?" is 30.

Given:

 

Calculation: 

The total number of all pizzas sold in the first two weeks = (150 + 130 + 100 + 150 + 200 + 100 ) = 830.

∴ The total number of all pizzas sold in the first two weeks is 830.

Given:

 

Calculation:

The number of Margherita pizzas sold in third and fourth weeks = (140 + 130) = 270 

The number of CHEESE N CORN pizzas sold in first and third weeks = (200 + 160) = 360

So, the ratio between them = 270 ∶ 360 = 3 ∶ 4

∴ The ratio between the number of Margherita pizzas sold in third and fourth weeks, and the number of CHEESE N CORN pizzas sold in first and third weeks is 3 ∶ 4.

Given:

 

Calculation: 

Total number of Margheritas sold in the second, third and fourth weeks = (150 + 140 + 130) = 420

So, the average = (420 ÷ 3) = 140

∴ The average number of Margheritas sold in the second, third and fourth weeks is 140.

Given:

 

Calculation:

The number of Golden Delight pizzas sold in the first and the second week is = (150 + 130) = 280

The number of Golden CHEESE N CORN sold in the first and the second week is = (200 + 100) = 300 

So, the difference = (300 - 280) = 20

So, the required percentage = (20/300) × 100% = 6.66%

∴ Golden Delight sold 6.66% less than CHEESE N CORN.

Given:

 

Calculation:

The total number of pizzas sold in first week = (150 + 100 + 200) = 450

The total number of pizzas sold in fourth week = (160 + 130 + 170) = 460

So, the difference between them = (460 - 450) = 10

∴ The difference between the number of all pizzas sold by Pizza Hut in the first week and the fourth week is 10.

Shortcut Trick

Weight of New Player = Weight of Replaced Player + (Total Players × Increase in Average)

Weight of New Player = 55 + (12 × 1/3)

Weight of New Player = 55 + 4 = 59 kg

∴ The correct answer is 59 kg.

Alternate Method

Given:

Number of players (n) = 12

Weight of player replaced = 55 kg

Average weight increase = 1/3 kg

Calculations:

⇒ Total weight increase = Number of players × Increase in average

⇒ Total weight increase = 12 × 1/3 = 4 kg

⇒ Weight of new player = Weight of replaced player + Total weight increase

⇒ Weight of new player = 55 + 4 = 59 kg

∴ The correct answer is 59 kg.

Additional Information

Net Change in Sum

When one member is replaced, the Total Sum changes by the difference between the new value and the old value: (New Value − Old Value) = n × (Change in Average).

Average Concept

Average = Sum of all observations ÷ Number of observations. If the average increases, the new value must be greater than the replaced value.

Given:

Rate of Interest = 5%

Time period = 3 years

Difference between the Simple Interest and Compound Interest = Rs.244

Formulae Used:

If P = Principal,

R= Rate of Interest, and 

n = number of years;

Then we can write:

When the interest is compounded annually, the amount is obtained as:

Amount = P × [1 + (R/100)]ⁿ, and 

The Compound Interest (CI) is obtained as:

CI = Amount - P.

Also, the Simple Interest (SI) is given as:

SI = (P × n × R)/100

Calculation:

The amount, when interest is compounded annually, is calculated as:

Amount = P × [1 + (5/100)]n

The Compound Interest (CI) is, hence, calculated as:

CI = P × [1 + (5/100)]³ - P 

⇒ CI = P × [(1.05)3 - 1]

⇒ CI = 0.157625P      ----(i)

The Simple Interest (SI) is calculated as:

SI = (P × 3 × 5)/100 

SI = 0.15P      ----(ii)

From equations (i) and (ii)

CI -SI = 0.157625P - 0.15P 

⇒ CI -SI = 0.007625P      ----(iii)

∵ It is given that the difference between the CI and the SI = Rs. 244,

From equation (iii), we get

0.007625P = 244

⇒ P = 244/0.007625

⇒ P = 32000

∴ The principal sum is Rs.32,000

Given:

Discount = Rs. 100

Shopkeeper earns profit = 140%

Profit% if sold at no discount = 220%

Calculation:

Let the CP be 100%

SP if profit is 140% = 240%

SP if profit is 220% = 320%

Difference in SP = Discount of Rs. 100

So, 220%  – 140% = Rs. 100

⇒ 80% = Rs. 100

Then 100% = Rs. (100/80) × 100

⇒ Rs. 125

∴ CP of the article is Rs. 125

Given:

Distance A and B is = 162 kms

Both trains meet after 6 hours

Relative speed:

Relative speed of two trains = 162/6 km/hr

⇒  27 km/hr

Calculation:

Let the speed of slower train be x km/hr

Speed of faster train = (x + 8) km/hr

So, x + (x + 8) = 27 km/hr

⇒ 2x + 8 = 27 km/hr

⇒ 2x = 19 km/hr

⇒ x = 19/2 km/hr

Speed of the faster train = (19/2) + 8 km/hr

⇒ 35/2 km/hr

∴ Speed of faster train is 35/2 km/hr

Shortcut Trick

Efficiency ratio A : B = 3 : 1

Time ratio A : B = 1 : 3 (Inverse of efficiency)

Difference in time units = 3 − 1 = 2 units → 60 days

1 unit = 30 days. So, A takes 30 days and B takes 90 days.

Together (XY / X+Y) = (30 × 90) ÷ (30 + 90) = 2700 ÷ 120 = 22.5 days.

∴ The correct answer is 22.5 days.

Alternate Method

Given: Efficiency of A is 3 times B. Time difference is 60 days.

Calculation:

⇒ Let time taken by B = x days, then A = x − 60 days.

⇒ Ratio of time A : B = 1 : 3

⇒ (x − 60) / x = 1 / 3

⇒ 3x − 180 = x

⇒ 2x = 180 ⇒ x = 90 days (Time for B)

⇒ Time for A = 90 − 60 = 30 days.

⇒ Total Work = LCM(30, 90) = 90 units.

⇒ Combined Efficiency = 3 + 1 = 4 units/day.

⇒ Time taken together = 90 ÷ 4 = 22.5 days.

∴ The correct answer is 22.5 days.

Additional Information

Efficiency and Time Relation

Efficiency is inversely proportional to the time taken to complete a task. If efficiency ratio is x:y, the time ratio is y:x.

Work from Efficiency

Total Work = Efficiency × Time. This is the fundamental unit for solving all Time and Work problems.

Combined Work Formula

For two people taking x and y days respectively, the time taken together is (x × y) ÷ (x + y).

Given:

The ratio of number of students of class M and N is 5 : 6.

Number of students of class M is increased by 30%

Number of students of class N is increased by 12600.

Concept used:

Here we will be using the fundamental concept of ratio.

Calculation:

Let the number of students in class M and N be 5x and 6x respectively

Number of students in class M after the increase = 5x + [(30/100) × 5x] = 5x + 1.5x = 6.5x

Number of students in class N after the increase = (6x + 12600)

As the ratio of number of students of both classes still remains 5 : 6

6.5x/(6x + 12600) = 5/6

⇒ 6.5x × 6 = 5 × (6x + 12600)

⇒ 39x = 30x + 63000

⇒ 9x = 63000

⇒ x = (63000/9)

⇒ x = 7000

∴ The number of students of class N = 6 × 7000 = 42000

Let the CP of both the bikes is x and y

x + y = 175000

According to question

120 % of x = 130% of y

\( \Rightarrow \frac{{120x}}{{100}}\) = \(\frac{{130y}}{{100}}\)

\( \Rightarrow \frac{x}{y} = \frac{{13}}{{12}} = \frac{{13m}}{{12m}}\)

⇒ 13m + 12m = 1,75,000

⇒ m = 7,000

CP of first bike = 91000

CP of 2^nd bike = 84000

∴ Required difference = 7000

Given:

Present age of Shivali and Tanisha = 11 : 7

After 8 years age of Shivali and Tanisha = 15 : 11

Calculation:

Let the present age of Shivali and Tanisha be 11x and 7x respectively

According to question,

\(\frac{{11x + 8}}{{7x + 8}} = \frac{{15}}{{11}}\)

⇒ 11 (11x + 8) = 15 (7x + 8)

⇒ 121x + 88 = 105x + 120

⇒ 16x = 32

⇒ x = 2

Now

∴ Difference between their ages = 11x - 7x = 4x

⇒ 4x = 4 × 2 = 8 years

Given:

25% books are of Social Science.

The number of Reasoning book are 280.

Concept Used:

Remaining number of books = [(100 - percentage%)/100] × Initial number of books

Calculation:

Let the total number of book be x.

The number of Social Science books = 25/100 × x = x/4

The Remaining number of books = x - x/4 = 3x/4

The number of General Science books = 16/100 × 3x/4 = 3x/25

The Remaining number of books = 3x/4 - 3x/25 = 63x/100

The number of Mathematics books = 63x/100 × 1/9 = 7x/100

The Remaining number of books = 63x/100 - 7x/100 = 56x/100

The number of Reasoning book are 280.

⇒ 56x/100 = 280

⇒ x = 500

∴ The total number of book in the store is 500.

 

Let the total percentage of the book be 100.

25% of books are of Social Science.

The Remaining percentage of books = 100 - 25 = 75%

The percentage of General Science books = 16/100 × 75 = 12%

The Remaining percentage of books = 75 - 12 = 63%

The percentage of Mathematics books = 63 × 1/9 = 7%

The Remaining percentage of books = 63 - 7 = 56%

The number of Reasoning book is 280.

⇒ 56% = 280

⇒ 1% = 5

⇒ 100% = 500

∴ The total number of book in the store is 500.

The number of Reasoning book is 280.

⇒ 100 × (100 - 25)/100 × (100 - 16)/100 × (1 - 1/9) = 280

Given:

The initial investment of Ajay = ₹ 35000

The initial investment of Rohit = ₹ 28000

The initial investment of Rohan = ₹ 56000

Total Profit = ₹ 154000

Concept used:

Profit = Investment × time period

Calculation:

Ajay invested 35000 for 12 months,

⇒ Total investment of Ajay = (35000 × 12)

⇒ 420000

Rohit invested 28000 for 6 months and (1/2) × (28000) for next 6 months,

⇒ Total investment of Rohit = [(28000 × 6) + (14000 × 6)]

⇒ 252000

Rohan invested 56000 for 6 months and (1/2) × (56000) for next 6 months,

⇒ Total investment of Rohan = [(56000 × 6) + (28000 × 6)]

⇒ 504000

Profit ratio = 420000 : 252000 : 504000

⇒ 5x : 3x : 6x = 14x

⇒ 14x = 154000

⇒ x = 11000

Profit of Rohit = 3x = 3 × 11000

∴ The profit of Rohit is ₹ 33000.

The car covers 75 km in one hour, but due to stoppage it is able to cover only 50 km in one hour

∴ Distance which the car is not able to cover due to stoppage = 75 - 50 = 25 km

⇒ Time which the car loses in stoppage = Time taken by it to cover 25 km distance

Time which the car loses in stoppage = 25/75 = 1/3 hr

Given:

The length and breadth of the field with the path are 95 m and 60 m respectively

The width of the path inside the mansion = 2.5 m

Formula used:

The area of rectangle = (Length × Breadth)

Calculation:

Area of the field with the path = 95 × 60 = 5700 m²

Area of the field without the path = 90 × 55 = 4950 m²

So, area of the path = Area of the field with the path - Area of the field without the path

⇒ (5700 – 4950) m²

⇒ 750 m²

So, the cost of gravelling the path = area of the path × cost per meter

⇒ (750 × 3) = Rs. 2250

∴ The cost of gravelling the path is Rs. 2250.
