10) Answer (D)
Sum of numbers in the regions common to 3 or 4 figures will give the number of persons who possess at least 3 of the 4 skills.
From the diagram, we can see that the sum is 7 +8+9 = 24
Therefore, option D is the right answer.
11) Answer (D)
Number of people who can do exactly 2 out of the 3 activities = 12 + 21 + 20 = 53.
Let the missing value be ‘x’.
Number of people who can do exactly one of the 3 activities = 23 + 7 + x = 30 + x.
It has been given that 30+x = 53
x = 23
Number of people who can paint = 12+8+20+23 = 63.
Therefore, option D is the right answer.
12) Answer (A)
The region common to 3 shapes will give us the number of people who have watched exactly 3 movies.
From the diagram, the number of people who have watched exactly 3 movies is 8+2+13 = 23. Hence, option A is the right answer.
13) Answer (B)
The area common to the circle, trapezium and the hexagon but not common to the triangle represents the people who can sing, swim and paint but cannot dance.
From the diagram, we can see that the number of such people is 14. Therefore, option B is the right answer.
14) Answer (B)
A person can be a writer, poet, singer and a doctor. Therefore, the Venn diagram must be 4 circles that intersect each other completely. Only option B satisfies this condition and hence, option B is the right answer.
15) Answer (C)
Some animals are both predator and prey. Frog eats insects and snakes eat frog. Therefore, frog is both a predator and prey.
Goat is a prey. Goats are herbivores and hence, they can be purely termed as preys. Tiger is an apex predator.
Therefore, the Venn diagram must contain 2 large intersecting circles and 3 small circles, one in each of the regions formed by the intersecting circles. Only option C satisfies this condition. Hence, option C is the right answer.
16) Answer (B)
We want intersection of rectangle, circle and triangle.
Thus required answer = 23
Hence, option B is the right choice.
17) Answer (A)
We want intersection of circle but avoid pentagon
Thus required answer = 31+ 46 + 21 + 4 = 102
Hence, option A is the right choice.
18) Answer (D)
We want intersection of triangle and circle but avoid rectangle.
Thus required answer = 38 + 21 = 59
Hence, option D is the right choice.
19) Answer (B)
Boats, cars and planes are types of vehicles. Sedan is a type of cars. Therefore, the diagram must contain 1 large circle (to represent vehicles), 3 smaller non-intersecting circles inside the larger circle (to indicate boats, cars and planes). One of the smaller circles must contain a smaller circle inside it (to indicate sedans). Only option C satisfies these conditions and hence, option C is the right answer.
20) Answer (B)
All apples are fruit. Some cider will be made of fruits and apple.
Hence, option B is the right choice.
