LIC ADO Mains Memory Based Paper (Held On: 11 August 2019) (Previous Year Paper)

Six persons = M, N, O, P, Q & R

1. The rectangle block was kept at 3^rd position.

2. Only one person kept a block between M and the person who kept the rectangle block.

3. M who placed hexagon was just below Q.

Case 1:

Case 2:

4. The circular block was kept by R just below M.

(So,case 1 is invalid. Move ahead with case 2.)

5. The triangle was kept at an even position just after P, but not on the top.

6. The difference in the position of the square block and the position at which N kept the block is 4.

Thus, R kept the circular block.

Six persons = M, N, O, P, Q & R

1. The rectangle block was kept at 3rd position.

2. Only one person kept a block between M and the person who kept the rectangle block.

3. M who placed hexagon was just below Q.

Case 1:

Case 2:

4. The circular block was kept by R just below M.

(So,case 1 is invalid. Move ahead with case 2.)

5. The triangle was kept at an even position just after P, but not on the top.

6. The difference in the position of the square block and the position at which N kept the block is 4.

Thus, octagon was kept immediately below the triangular block.

Six persons = M, N, O, P, Q & R

1. The rectangle block was kept at 3rd position.

2. Only one person kept a block between M and the person who kept the rectangle block.

The least possible Venn diagram is:

Conclusions:

I. Some Colorful are not Colors → False (Some Colors are Bright and All Bright are Colorful, so the Colorful which is Bright are also Color, so this is definitely false).

II. All Sketches being Bright is a possibility → True (Some Colorful are not Sketches, but there is no restriction of Sketches being part of Bright or Colorful).

III. Some Colors being Sketches is a possibility → True (As, no direct relationship between the two is given).

Hence, Both Conclusion II and III follows.

The least possible Venn diagram is:

Conclusions:

I. Some Idly are not Vada → True (As, Only a few Idly are Vada is given which means Some Idly are Vada and Some Idly are not Vada, so this is a definite conclusion).

II. Some Tasty can be Vada → True (The possibility is true, as we know that Some Vada cannot be part of Tasty, but don't know about any negative relationship of Tasty with Vada).

III. All Tasty being Idly is a possibility → True (The possibility is true, as no direct relationship between the two is given).

Hence, All Conclusion follows.

The least possible Venn diagram is:

Conclusions:

I. Some Girls are Pretty → False (This is possible but not definite).

II. Some Beautiful are not Bad → True (Some Beautiful are Pretty and No Pretty is Bad, so the part of Beautiful which is Pretty will never be Bad, so this is definitely true conclusion).

III. All Bad being Pretty is a possibility → False (The possibility is false, as Pretty and Bad both have relationship of No with each other).

Hence, Only Conclusion II follows.

The least possible Venn diagram is:

Conclusions:

I. Some Glue are Surgery → False (This is possible but not definite, as no direct relationship between the two is given).

II. Some Plastics are not Surgery is a possibility → False (The possibility is False, as All Plastics are Surgery and  Some Plastics are not Surgery is definitely false).

III. No Glue is Surgery → False (This is possible but not definite, as no direct relationship between the two is given).

Hence, Either I or III follows.

Hence, Point S is in South West direction with respect to Point P.

According to the given information, we get the following figure,

Shortest distance between point M and point T = NO + PR + QS = 4m + 2m + 3m = 9m

First point is in south - west of second point except in R - M.

Hence, R - M does not belong to the group.

According to the given information, we get the following figure,

Shortest distance between point M and point T = NO + PR + QS = 4m + 2m + 3m = 9m

Hence, ‘9m’ is the correct answer.

Persons: A, B, C, D, E and F.

1. C is lighter than only E. So, E is the heaviest.

2. D is heavier than A and F.

3. The weight of B and D are 75 kg and 65 kg respectively. So, B is heavier than D.

Either A or F is the lightest.

Hence, ‘Cannot be determined’ is the correct answer.

Persons: A, B, C, D, E and F.

1. C is lighter than only E. So, E is the heaviest.

2. D is heavier than A and F.

3. The weight of B and D are 75 kg and 65 kg respectively. So, B is heavier than D.

As, A + B = 135, so, A = 135 – 75 = 60

And D + F = 116, so, F = 116 – 65 = 51

Hence, A is the 2^nd lightest.

According to the question

Given statement: A * B, B © C, C © D

On converting: A > B, B ≥ C, C ≥ D

On combining: A > B ≥ C ≥ D

Conclusions:     

I. D * B → D > B → False (As, B ≥ C ≥ D → B > D)

II. C @ A → C < A → True (As, A > B ≥ C → A > C)

Hence, only conclusion II is true.

According to the question

On converting: L < M, M = T, T < O

On combining: L < M = T < O

Conclusions: 

I. T @ L → T < L → False (As, L < M = T < O → L < T)

II. O $ M → O ≤ M → False (As, L < M = T < O → O > M)

Hence, Neither I nor II follows**.**

According to the question

Statements:       

C % F, F @ G, G © M

Conclusions:  

I. M % F        

II. C @ G

Given statement: C % F, F @ G, G © M

On converting: C = F, F < G, G ≥ M

On combining: C = F < G ≥ M

Conclusions: 

I. M % F → M = F → False (As, C = F < G ≥ M → clear relation between M and F can’t be determined)

II. C @ G → C < G → True (As, C = F < G → C < G)

Hence, only II follows.

Calculation:

The number of 12^th students passed from science department in central zone = 700

The number of 12th students passed from science department in south zone = 550

Total number of 12th students passed from science department = (700 + 550)

⇒ 1250

Total number of 12^th passed students in east zone = (5000 × 20/100)

⇒ 1000

Now,

Required percentage of passed students from science department in central and south zone to total number of students in east zone = [(1250 – 1000)/1000 × 100]

⇒ (250/1000 × 100)

⇒ 25%

∴ Required percentage is 25% more.

Calculation:

Total number of 12^th students passed in west zone = (5000 × 10/100)

⇒ 500

Number of 12^th students passed from commerce department in west zone = (500 – 250)

⇒ 250

Total number of 12th students passed in south zone = (5000 × 15/100)

⇒ 750

Number of 12th students passed from commerce department in south zone = (750 –  550)

⇒ 200

Total number of 12^th passed from commerce department in west and south zone = (250 + 200)

⇒ 450

Now,

5/6^th of the students of commerce department are girls in west and south zones = (450 × 5/6)

⇒ 375

Number of 12^th boys passed from commerce department in west and south zones together = (450 – 375)

⇒ 75

∴ Required number of 12^th passed boys is 75

Calculation:

The number of 12^th students passed from science department in east zone = 600

The number of 12th students passed from science department in west zone = 250

Total number of 12th students passed from science department in east and west zones = (600 + 250)

⇒ 850

Total number of 12^th passed students in central zone = (5000 × 25/100)

⇒ 1250

The number of 12^th passed students from commerce department in central zone = (1250 – 700)

⇒ 550

Now,

The difference between the total number of 12th students passed from science department in east and west zones together and the number of 12th students passed from commerce department in central zone = (850 – 550)

⇒ 300

∴ Required difference is 300

Calculation:

Let the number of art students be x

Then,

Total number of 12^th students passed in north zone = (5000 × 30/100)

⇒ 1500

The number of 12^th students passed from commerce department = (1500 – 850)

⇒ 650

The number of 12^th students passed from science department in north zone = 850

According to the question

⇒ 650 + x = 3 × 850

⇒ 650 + x = 2550

⇒ x = (2550 – 650)

⇒ x = 1900

Now,

Total number of 12^th students passed in north zone = (1500 + 1900)

⇒ 3400

Required percentage = (1900/3400 × 100)

⇒ 55.88%

∴ The number of 12th students passed from art department from north zone to the total number of 12th students passed in north zone is 55.88%

Calculation:

The total number of 12^th students passed in west zone = (5000 × 10/100)

⇒ 500

The number of 12^th students passed from commerce department in west zone = (500 – 250)

⇒ 250

The total number of 12th students passed in east zone = (5000 × 20/100)

⇒ 1000

The number of 12^th students passed in commerce department in east zone = (1000 – 600)

⇒ 400

The total number of 12th students passed from commerce department in east and west zones = (400 + 250)

⇒ 650

The average number of 12th students passed from commerce department in east and west zones = (650/2)

⇒ 325

Required ratio = (500 : 325)

⇒ 20 : 13

∴ The ratio of the total number of 12th students passed in west zone and the average number of 12th students passed from commerce department in east and west zones is 20 : 13

According to the question,

The number of students who passed in Maths and Science only = (14% + 31%) × 1800

The number of students who passed in Maths and Social only= (13% + 31%) × 1800

The number of students who passed in Social  and Science only= (12% + 31%) × 1800

For exactly two subjects, we have to neglect the students who passed in all the three subjects = 31% 

The number of students who passed only two subjects  = (13% + 12% + 14%) × 1800

The number of students passed who failed in all three subjects 

= 1 - {P(A) + P(B) + P(C) + P(A ∪ B  ∪ C) + P( A ∪ B) + P(A ∪ C) + P(B∪ C)}  

The number of students passed who failed in all three subjects = 6%

The number of students who failed in all three subjects = 6% × 1800 = 108.

The number of students who passed in Maths and Science = (14% + 31%) × 1800

The number of students who passed in Maths and Social = (13% + 31%) × 1800

The number of students who passed in Social  and Science = (12% + 31%) × 1800

Here, the question is exactly two subjects so we have to neglect all three subjects passed students 31% we are not considering

The number of students who passed only two subjects  =(13% + 12% + 14%) × 1800

⇒ 39% of 1800

⇒ 39/100 × 1800

⇒ 702

∴ The number of students who passed exactly two subjects = 702

The number of students who passed in only Maths = 7% of 1800

The number of students who passed in only Science = 9% of 1800

The number of students who passed in only Social  = 8% of 1800

So, the number of students who passed in only one subject = (7% + 9% + 8%) of 1800

⇒ 24% of 1800 

⇒ 432

∴ The number of students who passed in only one subject = 432

The number of students who passed only Science = 9% of 1800

The number of students who passed in all subjects together = 31% of 1800

The number of students who passed in Science and Maths only = 14% of 1800

The number of students who passed in Science and Social only =  12% of 1800

The number of students who passed in subject Science  = (9% + 12% + 14% + 31% ) of 1800

⇒ 66% of 1800

⇒ 1188

∴ The number of students who passed in Science subject =  1188

Given that,

The total number of students = 2500

The number of students who passed all three subjects = 31% of 2500 

⇒ 31/100 × 2500

⇒ 775

∴ The number of students who passed all three subjects = 775

Amount = P(1 + r/100)ⁿ = 120000 

Amount = 24000 × ( 1 + 50/100)ⁿ = 120000

⇒ (1.5)⁴ = 5.0625 ≈ 5

∴ approximately he needs 4 years to buy the bike.

Shortcut Trick

Area of circle = (22/7) × 7² = 154 cm².

Area of rectangle = 154 − 84 = 70 cm².

Let width = x, then length = x + 3. So, x(x + 3) = 70.

By inspection, 7 × 10 = 70, where 10 − 7 = 3. Thus, length = 10 cm.

∴ The correct answer is 10 cm.

Alternate Method

Given: Radius (r) = 7 cm, Difference in areas = 84 cm², Length (L) = Width (W) + 3 cm.

Formula Used: Area of circle = πr²; Area of rectangle = L × W.

⇒ Area of Circle = (22/7) × 7 × 7 = 154 cm².

⇒ Area of Rectangle = 154 − 84 = 70 cm².

⇒ L × W = 70

⇒ (W + 3) × W = 70

⇒ W² + 3W − 70 = 0

⇒ W² + 10W − 7W − 70 = 0

⇒ W(W + 10) − 7(W + 10) = 0

⇒ W = 7 cm (ignoring negative value)

⇒ Length = 7 + 3 = 10 cm.

∴ The correct answer is 10 cm.

Additional Information

Properties of Rectangles

Perimeter of a rectangle is 2 × (length + width). The diagonals are equal and bisect each other.

Circle Mensuration

Circumference of a circle = 2πr. For a radius of 7 cm, the circumference is always 44 cm and the area is 154 cm².

Quadratic Roots Shortcut

For x² + bx + c = 0, if c is negative, the roots have opposite signs. Find factors of c that differ by b.

Ratio of Pupils in class I and II = 3 : 5         ----(1)

Ratio of Pupils in class II and III = 7 : 11        ----(2)

To find the ratio for all the three class, we will have to make the ratio of Class II common for both the given ratio.

Multiply equation (1) by 7 and equation (2) by 5

∴ Ratio of Pupils in class I and II = 21 : 35

∴ Ratio of Pupils in class II and III = 35 : 55

So, pupils in class I, II and III are in ratio 21 : 35 : 55

Let the common multiplying factor be x.

So, no. of pupils in these classes are 21x, 35x, 55x respectively.

Total no. = 333 = 21x + 35x + 55x

⇒ 111x = 333

⇒ x = 3

Looking at the proportion, highest no. of pupils are in class III.

∴ No. of pupils in class III = 55x = 55 × 3 = 165

Given that:

Speed of first train = 72 km/hr

Speed of second train = 54 km/hr

Both the train are moving in opposite direction to each other. They crosses in 20 sec.

Formula:

Relative speed = sum of the speed

Distance = speed × time

Calculation:

Let the length of the first train is 4x

Then, length of the second train = 3x

trains are going in opposite direction

So, the relative speed = 72 + 54 = 126 km/hr

= 126 × 5 / 18 = 35 m/sec

distance travelled by the trains in crossing each other = relative speed × time

⇒ ( 4x + 3x ) = 35 × 20

⇒ 7x = 700

⇒ x = 100 meter

length of the first train = 4x = 400 meter

Length of the second train = 3x = 300 meter

If the first train passes a platform of length L meter in 1 minute or 60 second

Then, speed = total distance travelled by the train in crossing the platform / time

⇒ 72 ×( 5 / 18 ) = ( 400 + L ) / 60

⇒ 400 + L = 20 × 60

⇒ L = 1200 – 400 = 800 meter

∴ Length of the platform is 800 meters.

• "This G-20 summit is an opportunity to display India’s capability before the world in a holistic manner.
• "Recently, the minister had discussions with all the party leaders in a very ________ atmosphere."
• The blank is preceded by a modifier (very) and followed by a noun (atmosphere)

The correct answer is Integral

Explanation –

• The passage is about -" Food Science & Technology''.
• The first passage is regarding the commitment of food science to its advancement that was necessary for evolution.

Key Points

• Let's find out which option should be used in the given blank space by knowing the meanings of all the vocab words →

          Peripheral means relating to or situated on the edge or periphery of something.

          Integral means necessary to make a whole complete; essential or fundamental.

          Structural means relating to or forming part of the structure of a building or other item​.

          Unified means make or become uniform or whole.

• " The commitment of food science and technology professionals.............. contributing to healthier people everywhere is (1)_____to that evolution." If we try to put all the words in the blank one by one, we find that Peripheral and Structural are not suitable options because both words mean -relating to an edge or part of something.
• Unified means make something or become uniform that is not related to the passage.
• Integral means necessary to make which is the suitable option for the fill in the blank.

So the sentence will become " The commitment of food science and technology professionals to advancing the science of food, ensuring a safe and abundant food supply, and contributing to healthier people everywhere is integral to that evolution."

The correct answer is option 3, i.e. Foraging

Explanation –

• The passage is about -" Food processing & Technology''.
• The third passage is regarding how the world has progressed through hunter-gatherer, agricultural, and industrial stages to providers of goods and services.

Key Points

• Let's find out which option should be used in the given blank space by knowing the meanings of all the vocab words →

          Pasturage means covering the land with grass and other lower plants for grazing animals, especially cattle or sheep.

          Scavenge means search for and collect (anything usable) from discarded waste.

          Foraging means the acquisition of food by hunting, fishing, or the gathering of plant matter.

          Cultivating means prepare and use (land) for crops or gardening.

• "This progression has been catalyzed by the cultural and social evolution of mankind and the need to solve specific societal issues, such as the need for preservation to free people from (2)_____for food." if we try to put all the words in the blank one by one, we find that Pasturage will not fit here contextually because it means to cover the land with grass for grazing animals and the sentence is regarding the need for conservation of food.
• Scavenge will also not fit here contextually because it means the search for anything from discarded waste that is not related to the conservation of food.
• Foraging will fit here contextually because it means searching for food and provisions from different sources, which is related to the conservation of food.
• Option 4, i.e. Cultivating is also the wrong option because it is related to farming.

So the sentence will become, "**This progression has been catalyzed by the cultural and social evolution of mankind and the need to solve specific societal issues, such as the need for preservation to free people from foraging for food."

• "According to Harvard Univ. biological anthropologist Richard Wrangham, ...... cooking was (3)_____ by fermenting, drying, preserving with salt, and other primitive forms of food processing" if we try to put all the words in the blank one by one, we find that 'spiked' and 'build up' are not the suitable options because they mean to increase something in magnitude or size that is not suitable for the word "cooking" that is used in the sentence.
• Augmented is a suitable option because it means to increase the value. It makes sense with the word 'cooking'.
• Option 4 is not suitable here because it is the opposite of the word 'Augmented'.

So the sentence will become " Later, but still, during prehistoric times, cooking was augmented by fermenting, drying, preserving with salt, and other primitive forms of food processing, which allowed groups and communities to form and survive."
