Question 1

A clock shows the time 08:20. What time will its mirror image (mirror placed vertically on the right side) show?

Accepted Answer

To find the mirror image of a clock time, subtract the given time from 11:60. Here, 11:60 - 08:20 = 03:40. So the mirror image will show 03:40. Common mistake: students subtract from 12:00 getting 03:40 — coincidentally same here, but the standard method is 11:60. Another common error is reading 08:20 mirror as 07:40 by reversing digits incorrectly. The correct answer is 03:40.

Question 2

In a 3×3 figure matrix, each cell contains overlapping shapes. Row 1: Circle overlaps Square, Square overlaps Triangle, Triangle overlaps Circle. Row 2: Square overlaps Triangle, Triangle overlaps Circle, Circle overlaps Square. Row 3: Triangle overlaps Circle, Circle overlaps Square, ? . What should replace the question mark?

Accepted Answer

This is a cyclic permutation matrix where shapes rotate in a fixed sequence: Circle → Square → Triangle → Circle. In each row, the overlapping pair shifts by one position in the cycle. Row 1 starts with Circle-Square. Row 2 shifts to Square-Triangle. Row 3 shifts to Triangle-Circle. The missing cell should continue the pattern: Square overlaps Triangle.

Question 3

A 3×3 matrix shows patterns of line segments. Row 1: 1 line, 2 lines, 3 lines. Row 2: 2 lines, 4 lines, 6 lines. Row 3: 3 lines, 6 lines, ? lines. Additionally, each cell's lines are oriented differently: Row 1 all horizontal, Row 2 all vertical, Row 3 all diagonal. How many diagonal lines should replace the question mark?

Accepted Answer

This matrix has two independent patterns. Pattern 1 (count): Each row is a multiple of the row number. Row 1: 1×1, 1×2, 1×3. Row 2: 2×1, 2×2, 2×3. Row 3: 3×1, 3×2, 3×?. Following this, the missing value is 3×3=9. Pattern 2 (orientation): All cells in Row 3 must be diagonal. The answer is 9 diagonal lines.

Question 4

A 3×3 matrix contains cells with shapes and internal divisions. Row 1: Circle divided into 2 parts, Square divided into 3 parts, Pentagon divided into 4 parts. Row 2: Square divided into 3 parts, Pentagon divided into 4 parts, Hexagon divided into 5 parts. Row 3: Pentagon divided into 4 parts, Hexagon divided into 5 parts, ? . What should replace the question mark?

Accepted Answer

This matrix has two independent patterns: (1) Shape progression by sides: Each row shifts to the next shape in the sequence (3→4→5→6→7 sides). (2) Division count: Each cell's divisions equal the number of sides minus 1. Row 1: Circle(2 parts), Square(3 parts), Pentagon(4 parts). Row 2: Square(3 parts), Pentagon(4 parts), Hexagon(5 parts). Row 3: Pentagon(4 parts), Hexagon(5 parts), Heptagon(6 parts).
