If C is the Uncle, then Professor is :

- A.
Grandfather

- B.
A

- C.
B

- D.
Mother

Answer: Option A

**Explanation** :

The seat numbers on the dining table can be defined as below:

From b - if C is seated on seat no.5, then the one who is a professor is on the seat no. 6.

From f, g and d - C is a Director and E sits second to the left of C. Also, there is one person between C and Grandmother of Gargi. Therefore, Grandmother can be at seat no. 3 i.e. E or at seat no. 7.

The Grandmother is seated to the immediate left of D who is a actor. So, there are two cases possible here:

If Grand mother is at seat no. 3, then D is at seat no. 4(CASE I ) and

If the Grandmother is at seat no. 7, the D is at seat no. 1(CASE II)

From h - Father, who is a doctor is between Professor and Sister of Gargi.

In Case II where Grandmother is at seat no. 7, the two neighbours of Professor are C(Director) and Grandmother. So in this case Father(Doctor) can't be between professor and a sister. So Case II gets eliminated.

Therefore, Grandmother is at seat no. 3 i.e. E is a Grandmother and D is at seat no. 4. Also, Father is at seat no. 7 and sister of Gargi is at seat no. 1.

From c and g - G, an artist is a sister of Gargi and is at seat no. 1. F, who is a Business person is at seat no. 2. As there are on three females in Gargi's family i.e. Mother, Sister and Grandmother and as G is a sister and E is a Grandmother of Gargi, therefore F is a Mother of Gargi.

So D is an actor is a Brother of Gargi.

Therefore the arrangement will be:

Seat no. 1 - G/Artist/Sister

Seat no. 2 - F/Business Person/Mother

Seat no. 3 - E/Minister/Grand Mother

Seat no. 4 - D/Actor/Brother

Seat no. 5 - C/Director/Grandfather or Uncle

Seat no. 6 - A or B/Professor/Grandfather or Uncle

Seat no. 7 - A or B/ Doctor/ Father

A group of students A, B, C, D, E, F, G, H and I visit Sheesh Mahal in Jaipur and play a game of standing in a horizontal line in front of a mirror as per the directions seen in the reflection. The group consists of four girls and five boys and none of the boys are at the extreme end positions. All the boys stand together with no girl in between. A takes the lead and stands in the centre to give directions as per those seen in the reflection. Some other directions which A gives are :

(a) G is on the extreme left while A is to the immediate left of D.

(b) C stands one place to the right of A and is not a girl.

(c) H is second to the left of B and to the immediate right of G.

(d) E is not on the extreme ends and is not a girl.

(e) B always stands between two boys.

Which of the following statement is always true ?

- A.
F and I are girls

- B.
E is a boy but A is a girl

- C.
A and E stand together

- D.
C and I stand together

Answer: Option A

**Explanation** :

Starting from the left, the positions are:

1 2 3 4 5 6 7 8 9

A is the one who starts the game by standing in the middle i.e. at position 5.

As, all the directions are seen in mirror and the arrangement is done accordingly, therefore each instruction given will be interpreted in the opposite way.

For example if instruction says that A is third to the right of B, then A will be positioned third to the left of B.

From A - G is on the extreme right end i.e. on position no. 9 and D is on the immediate left of A i.e. on position no. 4.

From B - C is on the position no. 3 and is a boy.

From C - H is second to the right of B and on the immediate left of G i.e. H is at position no. 8 and B is at position no. 6.

From E - The person to the immediate left of B i.e. A and immediate right of B, both are boys.

As C is a boy and person to the immediate right of B is also a boy (who is fourth to the right of C) and as mentioned in the given instructions that all five boys are together with no girls in middle, so from position 3 to 7 all are boys.

From D - As E is not a girl and is not at extreme ends, therefore the only place possible for E is position no. 7.

Therefore as per the above explanation, the Arrangement will be

I/F I/F C D A B E H G

So, as per the given explanation the only statement that is true is F and I are girls.

From C - H is second to the right of B and on the immediate left of G i.e. H is at position no. 8 and B is at position no. 6.

From E - The person to the immediate left of B i.e. A and immediate right of B, both are boys.

As C is a boy and person to the immediate right of B is also a boy (who is fourth to the right of C) and as mentioned in the given instructions that all five boys are together with no girls in middle, so from position 3 to 7 all are boys.

From D - As E is not a girl and is not at extreme ends, therefore the only place possible for E is position no. 7.

Therefore as per the above explanation, the Arrangement will be

I/F I/F C D A B E H G

I is on the immediate right of C as per the reflection.

Hence, option (c).

**Answer the questions based on the information given below.**

In a building with various offices on 12 floors there are two lifts. Lift 1 halts at even numbered floors and Lift 2 at odd numbered. A, B, C and D have their offices on 2, 8, 7 and 11 floors respectively. The office reaching time for A and C is 9:10 am while for B and D is 9:15 am and 9:20 am respectively. The attendance will be marked on the floor office. The lift takes 30 seconds to cross from one floor to another and halts on the selected floor for 30 seconds. The employees have to complete 8 hours and 30 minutes per day and are allowed to be late in the morning up to a maximum of 30 minutes which has to be compensated for in the evening. They have to enter the building from Ground i.e. ‘0’ floor and it is not necessary that the lift is always available.

If A reaches the building at 9:08 am and Lift 1 is at the 6th floor with only B in it, at what time can A at the earliest leave from office on that given day ?

- A.
5:40 pm

- B.
5:42 am

- C.
5:47 pm

- D.
5:45 pm

Answer: Option D

**Explanation** :

The lift takes 1 minute to reach on 8th floor(where B gets down) and halts for 30 seconds there.

Now the lift takes 4 minutes to reach Groundd floor Where A bords the lift and halts for 30 seconds.

After that lift takes another 1 minute to reach the second floor.

So the total time taken by lift = 1 + 0.5 + 4 + 0.5 + 1 = 7 minutes

This means A will reach office by 9:15 and can leave office by 5:45.

Hence, option (d).

D steps into Lift 1 by mistake with A in it at 9:00 am at the ground floor and C is in Lift 2 at ground floor at the same time and realises only when the lift has started. Then approximately at what time will D reach office, if Lift 2 halts for additional 30 seconds after D boards it ?

- A.
9:16 am

- B.
9:14 am

- C.
9:11 am

- D.
9:10 am

Answer: Option B

**Explanation** :

Here C travels from Ground floor to the office and takes 3.5 minutes. Also it halts on the 7th floor for 30 seconds.

Now it takes another 3.5 minutes to reach ground floor and 30 seconds to halt there.

Therefore lift 2 will take total of 8 minutes and will take a start form ground floor at 9:08

Now, D travels to second floor from wrong lift and comes back to ground floor at 9:02 and 30 seconds. This means D is ready to baord lift 2 when it arrives.

As, lift 2 takes extra 30 seconds after D boards it, and D has to go on 11ths floor. Therefore total time taken by D to reach office is 5.5 + 0.5 = 6 minutes

So, Do will reach office by 9:14 am.

Hence, option (b).

**Answer the questions based on the information given below.**

In an organisation with three departments i.e. Marketing, Finance and HR, it was decided to shuffle the 70 employees between departments. To make optimum use of resources, the management assesses their capability based on their qualification. 3 employees can work in every department. 7 employees can work in Finance and Marketing only. 10 can work only in HR while the number of employees only in Marketing is double of that in only Finance. Employees in only Finance cannot be less than 10 while employees in Finance and HR only are three times of two less than that of Marketing and HR only. The organization has employees with all possible combinations of their capabilities.

**26. IIFT 2019 LRDI | LR - Venn Diagram**

How many employees at the maximum are capable to work in Finance ?

- A.
31

- B.
33

- C.
28

- D.
32

Answer: Option A

**Explanation** :

Let the employees who can work only oin Finance be x, therefore employees who can work only in Marketing is 2x.

Also let the employees who can work in Marketing and HR only be a, therefore employees who can work in Finance and Hr only is 3(a – 2) = 3a – 6

∴ 2x + x + 7 + 3 + 10 + a + 3a – 6 = 70

∴ 3x + 4a = 56

As no. of employees inFinance can't be less than 10, so there are two possible solutions, where x = 12 and K = 5 and x = 16 and k = 2. But of K is 2 then the employees who can work Finance and HR only will be zero.

Therefore x = 12 and K = 5

So no. of employees who can work only in Finance are 12 and no. of employees who can work only in Marketing are 24.

No. of employees who can work in Marketing and HR only are 5 and no. of employees who cana work in Finance and HR only are 3a – 6 = 9

no. of Employees capable of working in Finance = 7 + 3 + 9 + 12 = 31

Hence,option 1.

How many employees are capable to work in Marketing and HR only ?

- A.
1

- B.
5

- C.

- D.
7

Answer: Option B

**Explanation** :

Let the employees who can work only oin Finance be x, therefore employees who can work only in Marketing is 2x.

Also let the employees who can work in Marketing and HR only be a, therefore employees who can work in Finance and Hr only is 3(a – 2) = 3a – 6

∴ 2x + x + 7 + 3 + 10 + a + 3a – 6 = 70

∴ 3x + 4a = 56

As no. of employees inFinance can't be less than 10, so there are two possible solutions, where x = 12 and K = 5 and x = 16 and k = 2. But of K is 2 then the employees who can work Finance and HR only will be zero.

Therefore x = 12 and K = 5

So no. of employees who can work only in Finance are 12 and no. of employees who can work only in Marketing are 24.

No. of employees who can work in Marketing and HR only are 5 and no. of employees who cana work in Finance and HR only are 3a – 6 = 9

Number of employees capable of Working in Marketing and HR only are 5.

Hence, option (b).
