Q. If a 3x3 matrix is filled with consecutive integers starting from 1, what is the value at the position (2, 2)?
A.
4
B.
5
C.
6
D.
7
Solution
The matrix would be [[1, 2, 3], [4, 5, 6], [7, 8, 9]], so the value at (2, 2) is 5.
Q. If a matrix is arranged such that each element is the product of its row and column indices (starting from 1), what is the value at the position (3, 2) in a 4x4 matrix?
Q. If a matrix is arranged such that each element is the sum of the two elements directly above it, what is the value of the element in the second row, second column if the first row is [1, 1]?
A.
1
B.
2
C.
3
D.
4
Solution
The second row, second column is the sum of the two elements above it, which are both 1, so 1 + 1 = 2.
Q. In a 4x4 matrix, if the first row is [1, 2, 3, 4] and the second row is [5, 6, 7, 8], what is the sum of the elements in the third row if it follows the same pattern?
A.
9
B.
10
C.
11
D.
12
Solution
The third row would be [9, 10, 11, 12], and the sum is 9 + 10 + 11 + 12 = 42.
Q. In a direction sense puzzle, if you start facing north and turn 90 degrees clockwise, then 180 degrees counterclockwise, which direction are you facing?
A.
North
B.
East
C.
South
D.
West
Solution
Starting north, turning 90 degrees clockwise faces you east, then 180 degrees counterclockwise faces you south.
