Q42.Which of the following does not belong to the group?
Correct Answer: A
Figures B, C, and D are all diagrams of electrical connectors or components. Figure A is a diagram of a face, which does not belong to the group.
Q43.Determine the total number of triangles present in the given figure.
Correct Answer: D
The figure contains 8 small triangles, 4 medium triangles (composed of 2 or 3 small ones), 3 larger triangles inside the main shape, and 1 largest whole outline triangle, totaling 16 triangles.
Q44.Select the correct option to complete the split square pattern:
Correct Answer: C
When the left square is split down the middle, the missing right half must supply the mirror-image pieces so the two large triangles and small corner shapes join at the center. Option C correctly completes these triangles and the zig-zag.
Q45.Select the correct figure which completes the symmetrical triangular pattern:
Correct Answer: D
Option 4 is correct because it completes the symmetrical triangular line pattern radiating from the center, mirroring the other three quadrants.
Q46.Which figure completes the blank space of pattern (X) (rotations and corner triangles)?
Correct Answer: B
The shapes in the three visible boxes rotate clockwise by 90 degrees each step, and the black triangles in the corners also rotate. Option 2 continues this rotation accurately.
Q47.Select a figure which completes the pattern of figure (X):
Correct Answer: B
Option 2 correctly continues the line crossings and shading to complete the pattern of figure (X).
Q48.Select a figure which would complete the symmetrical design of (X):
Correct Answer: C
Option C (3) aligns with the intersecting lines of the existing quadrants to maintain overall symmetry and continuity.
Q49.Select a figure which completes the rotation and shading pattern:
Correct Answer: C
Option 3 (C) aligns with the rotation and shading sequence of the three-segment design in the previous rows and columns.
Q50.Identify the figure that completes the vertical and horizontal line pattern:
Correct Answer: C
The vertical and horizontal lines increase systematically. Option 3 has three vertical and three horizontal lines, which matches the logical progression.
Q51.If you write down all numbers from 1 to 100, how many times would you write the digit 3?

Q52.Which product is smaller in value?
Correct Answer: C
Calculations: A=64M, B=18.53M, C=16.02M, D=18.03M. The smallest product is 8008 x 2001 = 16,024,008.
Q53.How many English alphabet capital letters look exactly the same in a mirror?
