Q. In a constraint-based set of colors, if red and blue are included, which of the following colors could be excluded based on the constraint of primary colors?
A.
Green
B.
Yellow
C.
Purple
D.
Orange
Solution
Purple is a secondary color formed by mixing red and blue, thus it could be excluded if only primary colors are considered.
Q. In a constraint-based set, if the constraints are 'x is a positive integer and x is less than 10', which of the following is the largest element in the set?
A.
8
B.
9
C.
10
D.
7
Solution
The largest element in the set defined by the constraints is '9', as it is the largest positive integer less than 10.
Q. In a constraint-based set, if the constraints are modified to include only even numbers, which of the following would be the new set if the original set was {1, 2, 3, 4, 5, 6}?
A.
{2, 4, 6}
B.
{1, 3, 5}
C.
{1, 2, 3, 4, 5}
D.
{2, 3, 4, 5, 6}
Solution
The new set would be {2, 4, 6} as it includes only the even numbers from the original set.
Q. In a group of 50 people, 30 like reading fiction, 20 like reading non-fiction, and 5 like both. How many people do not like reading?
A.
15
B.
20
C.
25
D.
10
Solution
The number of people who like reading is |Fiction| + |Non-Fiction| - |Both| = 30 + 20 - 5 = 45. Therefore, those who do not like reading = 50 - 45 = 5.
Q. In a hybrid set scenario, if element x belongs to set A and element y belongs to set B, which of the following can be inferred about their relationship in the hybrid set?
A.
Element x is equal to element y.
B.
Element x and element y are both included in the hybrid set.
C.
Element x cannot be in the hybrid set.
D.
Element y is a subset of element x.
Solution
Both elements x and y can be included in the hybrid set as they belong to their respective sets.
Correct Answer:
B
— Element x and element y are both included in the hybrid set.
Q. In a hybrid set scenario, if element x is in set A and element y is in set B, which of the following can be inferred about their relationship in the hybrid set?
A.
Element x is equal to element y.
B.
Element x and element y are both in the hybrid set.
C.
Element x is not in the hybrid set.
D.
Element y is not in the hybrid set.
Solution
If both elements belong to their respective sets, they will also be included in the hybrid set.
Correct Answer:
B
— Element x and element y are both in the hybrid set.
