ESIC SSO Prelims Mock Test - 8 - Insurance Exams MCQ

1) Rashmi sits at corner having weight 50 kg & is immediate neighbour of Sia.
2) Aarti sits opposite to Sia.
Case 1:

Case 2:

3) The weights of the girls vary from 38 kg to 50 kg.
(38,39,40,41,42,43,44,45,46,47,48,49,50)

4) Sia’s weight is common multiple of 6 & 7.
(38,39,40,41,42,43,44,45,46,47,48,49,50; so, weight of Sia is 42 kg)

5) Sita’s weight is multiple of 5 but not an even number.
(38,39,40,41,42,43,44,45,46,47,48,49,50; so weight of Sita is 45 kg)

6) Weight of Ananya is a prime number but not less than 44 kg.
(38,39,40,41,42,43,44,45,46,47,48,49,50; so, weight of Ananya is 47 kg)

7) Difference between weights of Sia & Aarti is 7 kg.
(Aarti’s weight – Sia’s weight = 7 kg; Aarti’s weight is 49 kg)

[Note: Aarti’s weight cannot be less than Sia’s weight because the answer will not be within the range of the given weights]

8) The weight of the lightest girl is 11 kg less than Aarti.
(Only Radha is left so she must having the least weight so Aarti’s weight – Radha’s weight = 11 kg; so, Radha’s weight is 38 kg)

9) Radha sits diagonally to the heaviest girl.
10) Ananya sits immediate left of the girl who is lightest among all.
Case 2 is not correct because in that case, Ananya is not immediate left to Radha so Case 2 is eliminated.
3) Sia is not the immediate neighbour of Sita.
Case 1:

So, The weight of Sia is 42 kg.

Note:
I. Only few streets are roads.
The above statement implies that
Some streets are roads.
Some streets are not roads.

III. Each jumble is crossing.
The above statement implies that
All jumbles are crossing.
The least possible Venn diagram is given below:

Conclusions:
I. Some jumbles are streets. → False (as it is possible but not definite)
II. No crossing is street. → False (as it is possible but not definite)
III. Some roads are crossing. → True (Some roads that are jumbles are also crossing)
Hence, only conclusion III follows.

Given: Ten persons buy backpacks of three different companies.
Based on the given conditions, we get the following possibilities-
1. B, who buys a Wildcraft, buys the same as R. X and Y don’t buy either Wildcraft or Aristocrat. From these, we get-

2. M and Y buys backpacks of the same company. K buys a Wildcraft backpack. From these, we get-

3. G and K buy backpacks of the same company. Z doesn’t buy a Wildcraft or Skybags backpack. C buys a backpack of the same company as Z. W doesn’t buy a Skybags or Aristocrat backpack. From these, we get the final table as follows-

Members = A, B, C, D, E, F, G, H, and I
​1) There are three married couples in the family.
2) Both the parents of a person are alive.
3) C is the paternal uncle of E who is the only daughter of G.
Implies, E's father has a brother.
4) H is the paternal aunt of I who is the only daughter of C.
Implies, C is married and E's father has a brother (C) and a sister (H).
5) D is the daughter-in-law of B who is the father of H.
B is the father of C, H, and the father of E.
6) G is not married to D.
As G and D are not married couples and D is the daughter-in-law of B, implies, D is married to C.
7) F is the mother of A who is not a female member.
As we need to map two people in the family tree. One is the wife of B and the other is the partner of G. It is only possible if F is the wife of B and A if the father of E and the husband of G.
The family tree is shown below:

Hence, A is the brother of C.

Given number: 37825636748
Operation 1: The digits at the even position are increased by 1.
Operation 2: The digits in the number are arranged in increasing order(from left to right).

New number: 33355777888
The seventh element from the left end = 7
The fourth digit of the right of 7 is 8.
Hence, the correct answer is "8".

Venn diagram of the above question.

Conclusions:
I. Some car are not train - False (All car being train is a possibility is true, so some car are not train is false)
II. Some bus are not car - False (Here the relation between Car and Bus is not definite so we can say that All the bus being car is possible, when All the bus being car is possible so some bus are not car is definitely false)

Hence, neither I nor II follows.

Additional Information

'Only a few car is bike' means that some car are bike and some car are not bike but from this we cannot conclude that 'Some car are not train'. This is a possible statement but not definite.
We can draw the circle of car in the right side of bike which makes complete sense to the given statement, then 'Some car are not train' would become false.

Eight persons: Hema, Himanshu, Heera, Hari, Harish, Hitesh, Harry, and Hemant
Designations: MD, GM, AGM, DGM, Manager, AM, PO, and Clerk
1) At least four persons are senior to Harish who likes Fan.

As the above condition is not satisfied in case 2, it will get canceled.
8) Hema is junior to Himanshu who likes PK.
9) Harry does not like Udaan.

Final Arrangement:

Hence, Hitesh is the AGM in the bank.

All persons are facing north.
1) K sits 4th to the left of L. There is two person sit between L and G. So, there have two possibilities.


2) Three persons sit between L and Q.


3) The number of persons sitting between G and K is same as the number of persons sitting to the right of Q.


4) Only one person sits between L and P. Six persons sit between P and S and S sits right of P. So, Case (2) will be eliminated.

5) S is fourth left of T and S sits third to left of M. Both T and M are immediate neighbour of each other. So, Case (1b) will be eliminated.

6) The number of persons sitting to the right of M is same as the number of persons sitting to the left of K.

Hence, Q is sitting four left to the M in the row.

Final case:

After rearrangement-

So, None of them remain at the same place and C gets the 3^rd floor after rearrangement.

Given:
Sum of their ages = 70 years
The ratio of their ages = 7 ∶ 3

Calculation:
Let the age of Deepak and Suman be 7x and 3x respectively
Sum of their ages = 70
⇒ 7x + 3x = 70
⇒ 10x = 70
⇒ x = 70/10
⇒ x = 7
Now,
The age of Deepak be 7x
⇒ 7 × 7
⇒ 49
∴ The Age of Deepak will be 49 years.

Quantity 2:
Given:
The difference of their present ages = 15 years
8 years ago the ratio of their ages = 7 ∶ 4

Calculation:
Let the 8 years ago, the age of Deepak and Suman be 7x and 4x respectively
The difference of their ages = 15
⇒ 7x – 4x = 15
⇒ 3x = 15
⇒ x = 15/3
⇒ x = 5

Now,
The age of Deepak 8 years ago be 7x
⇒ 7 × 5
⇒ 35 years
Now,
The present age of Deepak = 35 years + 8 years
⇒ 43 years
∴ The Present age of Deepak will be 43 years.
The comparison of both the Result:
∴ Quantity I > Quantity II

Given:
COVID19 patients of three major cities of INDIA

Calculation:
Number of people who decided to go to Delhi = 5000 × 20% = 1000
Increase in number of COVID patients = 1000
Number of COVID patients in Delhi at present = 5000
Percentage increase = 1000/4000 × 100 = 25%

Based on the given table, we can calculate the number of Espresso and Cappuccino ordered at each coffee shop.

Calculation:
Total Coffees ordered in Brew = 2100.
60% of the coffees are ordered in Greenwood:
Coffees ordered in Greenwood = 2100 × 60% = 1260.
Remaining coffees are ordered in Lakewood:
Coffees ordered in Lakewood = 2100 - 1260 = 840.
Number of Espresso ordered in Greenwood = 290.
Total Espresso ordered in Brew = 735 (calculated earlier).
So, the number of Espresso ordered in Lakewood = 735 - 290 = 445.
Total Coffees ordered in Lakewood = 840.
Number of Cappuccinos ordered in Lakewood:
Coffees in Lakewood = Espresso + Cappuccino.
Therefore, number of Cappuccinos ordered in Lakewood = Total Coffees in Lakewood - Espresso in Lakewood.
Cappuccinos in Lakewood = 840 - 445 = 395.
Thus, the number of Cappuccinos ordered in Lakewood is 395.

Note: Here 1 means, the person is the heaviest and 6 means the lightest.
Here 1 means. The person is the tallest and 6 means the shortest.
1) B is heavier than only two people.

2) Only one person is heavier than D. B is shorter than of only D.

3) C is the only person taller than E.

4) As many people are heavier than A as are shorter than him.

5) F is not lighter than E, which means that F must be the heaviest person and E must be the second lightest person as no candidate gets the same position in the height and weight table.

So, from here we can conclude that 3 persons weigh between F and E.

Ten boys: A, B, C, D, E, F, G, H, I, and J
Girls: Monica, Surbhi, Sohini, Gitika, Charul, Pariniti, Sheena, Jazba, Namita, and Vaibhavshree
1) The one who likes Surbhi is sitting at one of the north facing ends.
2) A is facing the one, who sits second to the right of Surbhi.
3) A likes Gitika.
4) Gitika is sitting second to the right of B, who likes Monica.

5) The one who likes Vaibhavshree is facing in the north direction and the one who likes Namita is facing in the south direction.
6) C likes Namita, who is sitting opposite to the one, who likes Vaibhavshree.
So here we get two cases,

7) Jazba is sitting opposite to Monica.
8) E is to the immediate right of C.
Thus case 1 gets eliminated.
9) E is facing F.
10) G is sitting third to the right of F and is facing Pariniti.
11) H likes Vaibhavshree.
12) G likes Charul.

13) D is sitting second to the right of one, who likes Sheena.
We have only one position for this.

Hence, E likes Sohini is the correct pair.

Ten boys: A, B, C, D, E, F, G, H, I, and J
Girls: Monica, Surbhi, Sohini, Gitika, Charul, Pariniti, Sheena, Jazba, Namita, and Vaibhavshree

5) The one who likes Vaibhavshree is facing in the north direction and the one who likes Namita is facing in the south direction.
6) C likes Namita, who is sitting opposite to the one, who likes Vaibhavshree.
So here we get two cases,

7) Jazba is sitting opposite to Monica.
8) E is to the immediate right of C.
Thus case 1 gets eliminated.
9) E is facing F.
10) G is sitting third to the right of F and is facing Pariniti.
11) H likes Vaibhavshree.
12) G likes Charul.

13) D is sitting second to the right of one, who likes Sheena.
We have only one position for this.

As, D likes Jazba, the line G likes Jazba is odd one out.

Given:
We use the following symbols to denote the relation between parties:

1. The father-in-law of S, who is married to the son of U, has 2 grandchildren of the same gender.

2. X is the sister of R, who is the son of O.

3. R has 2 daughters.

4. Q is married to W.

5. T is the sister-in-law of P, who is married to V.

6. U is the mother of X.

7. Q is the father of S.

Combining all of them together, we get:

Hence, there are 4 males in the family.

In E < Z ≥ D = B ≥ A → Z ≥ A → so in this statement Z < A is definitely false.
In A > E < K ≥ B < Z → so in this statement clear relation between Z and A cannot be determined)
In Z ≤ D < E ≤ A < B → so in this statement Z < A is definitely true.
In A < E = D = K < Z → Z > A → so in this statement Z < A is definitely false.
In Z < B > D > K = A → so in this statement clear relation between Z and A cannot be determined)
Hence in expression Z ≤ D < E ≤ A < B, Z < A is definitely true.

1) B likes mango and lives on an even-numbered floor and more people live below him than above, which infers that B lives either on the 6th floor or 8th floor.
2) Two people live between C and D where the former lives below the latter on an even-numbered floor, which means that C lives below D.
3) As many people live above C as below H, which means equal number of people live above C, as live below H.
4) The one who likes vanilla lives on the bottommost floor which is neither E nor A.
5) Two people live between the one who likes blackcurrant and the one who likes mango flavor.

On Combining these sentences, we get 4 possible cases.

So, Case 1 and Case 2 get canceled here.
7) F likes strawberry and lives below D.
8) There are two floors between the one who likes badam and the one who likes pista, none of which is liked by C.
9) D lives above the one who likes butterscotch and below the one who likes badam flavor which is liked by E.
10) Since, only H is left so he will like chocolate, the only flavor left.

11) A does not like pista.
So again case 3 gets eliminated.

Final case:

So, Mango lies exactly between Badam and strawberry on the 6^th floor.

1) B likes mango and lives on an even-numbered floor and more people live below him than above, which infers that B lives either on the 6th floor or 8th floor.
2) Two people live between C and D where the former lives below the latter on an even-numbered floor, which means that C lives below D.
