Iq Funda answered |
The best relation between Travelers, Train, and Bus can be represented in a Venn diagram, where Travelers are represented as a larger circle containing both Train and Bus circles. This is because travelers can choose either train or bus as their mode of transportation, and some may use both. Here's the explanation:
Travelers
- Travelers are people who move from one place to another for various reasons, such as work, leisure, or other purposes.
Train
- A train is a mode of transportation that runs on a railway track and can carry passengers or goods.
- Some travelers may choose to travel by train due to various factors such as cost, comfort, or availability.
Bus
- A bus is a mode of transportation that runs on roads and can carry passengers.
- Some travelers may choose to travel by bus due to factors such as cost, convenience, or accessibility.
Venn Diagram: Option C
- In option C, we have a large circle representing Travelers, which includes two smaller circles representing Train and Bus.
- This diagram shows that there are travelers who use trains, travelers who use buses, and some travelers who may use both modes of transportation.
- This representation captures the relationship between travelers and their choice of transportation, whether it's by train, bus, or both.

G.K Academy answered |
Atleast 80 students study neither Spanish nor Mandarin.
Hence, maximum number of students who study atleast one language = 290 – 80 = 210
Hence, maximum number of students who study atleast one language = 290 – 80 = 210
Minimum number of students who study both languages = 100 + 120 – 210 = 10
∴ Maximum number of students who study Spanish but not Mandarin = 120 – 10 = 110
Maximum number of students who study both languages = smaller value of 100 and 120 = 100
∴ Minimum number of students who study Spanish but not Mandarin = 120 – 100 = 20
Hence, the range could be any number from 20 to 110.
Hence, option (a).

G.K Academy answered |
We know that x + y + z = T and x + 2y + 3z = R, where
x = number of members belonging to exactly 1 set = 70
y = number of members belonging to exactly 2 sets
z = number of members belonging to exactly 3 sets = 10
T = Total number of members
R = Repeated total of all the members = (40 + 50 + 60) = 150
Thus we have two equations and two unknowns. Solving this we get y = 25
x = number of members belonging to exactly 1 set = 70
y = number of members belonging to exactly 2 sets
z = number of members belonging to exactly 3 sets = 10
T = Total number of members
R = Repeated total of all the members = (40 + 50 + 60) = 150
Thus we have two equations and two unknowns. Solving this we get y = 25
So, 25 people belong to exactly 2 clubs.

Let the number of persons who do not take any juice and the number of persons who take all 4 types of juices be ‘x’.
As there are ‘x’ people who take atleast 4 types of juices there should be ‘2x’ people who take atleast 3 types of juices.
This means the number of people who take exactly 3 types of juices = 2x – x = x.
As there are ‘2x’ people who take atleast 3 types of juices there should be ‘4x’ people who take atleast 2 types of juices.
This means the number of people who take exactly 2 types of juices = 4x – x – x = 2x.
As there are ‘4x’ people who take atleast 2 types of juices there should be ‘8x’ people who take atleast 1 type of juices.
This means the number of people who take exactly 1 type of juices = 8x – 4x = 4x.
Thus the total number of people in the Gym = x + 4x + 2x + x + x = 9x.
9x = 207 => x = 23.
The number of people who take exactly 2 types of juices = 2x = 46.
As there are ‘x’ people who take atleast 4 types of juices there should be ‘2x’ people who take atleast 3 types of juices.

Aim It Academy answered |
Let total number of families in the village be T
Number of families own agricultural land, n(A) = 0.22T
Number of families own agricultural land, n(A) = 0.22T
Number of families own mobile phone, n(M) = 0.18T
Number of families own both agricultural land and mobile phone, n(A ⋂ M) = 1600
Number of families own agricultural land or mobile phone, n(A ⋃ M) = T – 0.68T = 0.32T
∴ n(A ⋃ M) = n(A) + n(M) – n(A ⋂ M)
∴ n(A ⋂ M) = 0.08T
0.08T = 1600 ⇒ T = 20000
Hence, option (a).

Given Information:
- Total number of students admitted to the 2018-19 MBA batch = 400
- Number of students who did not choose "Business Statistics" = 200
- Number of students who did not choose "International Management" = 100
- Number of students who did not choose either subject = 80
Calculations:
Let's denote:
- Number of students who chose both "Business Statistics" and "International Management" as x
- Number of students who chose only "Business Statistics" as y
- Number of students who chose only "International Management" as z
From the given information, we can create the following equations:
x + y = 200 (Total number of students who chose "Business Statistics")
x + z = 100 (Total number of students who chose "International Management")
x + y + z + 80 = 400 (Total number of students admitted)
Now, we can solve these equations to find the values of x, y, and z.
From the first two equations:
y = 200 - x
z = 100 - x
Substitute these values in the third equation:
x + (200 - x) + (100 - x) + 80 = 400
300 - x + 80 = 400
380 - x = 400
-x = 20
x = 20
Therefore, the number of students who chose both "Business Statistics" and "International Management" is 20.
Therefore, the correct answer is option B) 180.
- Total number of students admitted to the 2018-19 MBA batch = 400
- Number of students who did not choose "Business Statistics" = 200
- Number of students who did not choose "International Management" = 100
- Number of students who did not choose either subject = 80
Calculations:
Let's denote:
- Number of students who chose both "Business Statistics" and "International Management" as x
- Number of students who chose only "Business Statistics" as y
- Number of students who chose only "International Management" as z
From the given information, we can create the following equations:
x + y = 200 (Total number of students who chose "Business Statistics")
x + z = 100 (Total number of students who chose "International Management")
x + y + z + 80 = 400 (Total number of students admitted)
Now, we can solve these equations to find the values of x, y, and z.
From the first two equations:
y = 200 - x
z = 100 - x
Substitute these values in the third equation:
x + (200 - x) + (100 - x) + 80 = 400
300 - x + 80 = 400
380 - x = 400
-x = 20
x = 20
Therefore, the number of students who chose both "Business Statistics" and "International Management" is 20.
Therefore, the correct answer is option B) 180.

From the information given in the question, the following Venn Diagram can be constructed:
So, in order to maximize the number of families that own only a bike, we can put the remaining 44 families in ‘only bike’ region.
So, in order to maximize the number of families that own only a bike, we can put the remaining 44 families in ‘only bike’ region.
Similarly, in order to minimize the number of families that own only a bike, we can put the remaining 44 families in ‘only scooter’ region.
So, the maximum number of families that own only a bike is 44 and the minimum number of families that own only a bike is 0.
So, sum = 44 + 0 = 44

Understanding the Problem
To solve the problem, we need to set up variables for the number of students in each category of elective subjects.
Given Data
- Total students = 360
- Students not taking any subject = 72
- Students taking Green Supply Chain (G) = 120
- Students taking Corporate Governance (C) = 124
- Students taking all three subjects = 12
- Let:
- x = Students taking G and C but not Global Climate Change (X)
- y = Students taking G and X but not C
- z = Students taking X and C but not G
Relationships between the groups
- According to the problem:
- \( x = 2y \)
- \( x = z \)
- \( y = 12 \) (since 12 students take all three subjects)
Calculating Students in Each Category
Using the relationships:
- \( y = 12 \) (students taking all three)
- \( x = 2y = 2 \times 12 = 24 \)
- \( z = x = 24 \)
Calculating Total Students Taking Each Subject
Using the inclusion-exclusion principle:
- Total taking G and C = \( 120 + 124 - (x + y + z + 12) \)
Set the equation:
- \( 120 + 124 - (24 + 12 + 24 + 12) = 360 - 72 \)
- Solve for students taking Global Climate Change only:
Final Calculation
Total students studying:
- \( G + C + X - G \cap C - G \cap X - C \cap X + G \cap C \cap X = 288 \)
Thus, the students studying Global Climate Change only = \( 360 - 72 - (students in G + C + both) = 104 \).
Conclusion
The number of students studying Global Climate Change & Business only is:
Answer: 104 (Option B).

Relationships between the groups
- According to the problem:
- \( x = 2y \)
- \( x = z \)
- \( y = 12 \) (since 12 students take all three subjects)
Calculating Students in Each Category
Using the relationships:
- \( y = 12 \) (students taking all three)
- \( x = 2y = 2 \times 12 = 24 \)
- \( z = x = 24 \)
Calculating Total Students Taking Each Subject
Using the inclusion-exclusion principle:
- Total taking G and C = \( 120 + 124 - (x + y + z + 12) \)
Set the equation:
- \( 120 + 124 - (24 + 12 + 24 + 12) = 360 - 72 \)
- Solve for students taking Global Climate Change only:
Final Calculation
Total students studying:
- \( G + C + X - G \cap C - G \cap X - C \cap X + G \cap C \cap X = 288 \)
Thus, the students studying Global Climate Change only = \( 360 - 72 - (students in G + C + both) = 104 \).
Conclusion
The number of students studying Global Climate Change & Business only is:
Answer: 104 (Option B).

Let the Venn diagram be as shown in the figure,
No one can take all three rides, hence g = 0.
No one can take all three rides, hence g = 0.
22 people take rides A and B,
∴ d = 22
∴ d = 22
25 people take rides A and C,
∴ f = 25
∴ f = 25
50 people take ride C,
∴ c = 50 – 25 = 25.
∴ c = 50 – 25 = 25.
40 people don’t take A or B or both,
∴ 40 = c + h
⇒ h = 40 – 25 = 15
∴ 40 = c + h
⇒ h = 40 – 25 = 15
∴ Total number of people visiting the park = (77 + 55 + 50 – 25 – 22) + 15 = 150.
Hence, option (d).

Let the number of days in the vacation be x
They played tennis for x - 14 days
They did yoga for x - 24 days
So, they did yoga or played tennis for x - 14 + x - 24 = 2x - 38 days
2x – 38 = 22
=> x = 30
They played tennis for x - 14 days
They did yoga for x - 24 days
So, they did yoga or played tennis for x - 14 + x - 24 = 2x - 38 days
2x – 38 = 22
=> x = 30
