Explanation

The statement says "All efficient typists are good organizers," meaning every efficient typist is included in the group of good organizers.

So it's logically valid to say that some efficient typists are good organizers (since “all” includes “some”).

Explanation

 The full square is divided into four parts, forming a symmetrical pattern of lines radiating from the center.

- Each quadrant contributes to the full radial design.

- The missing part (X) must continue the lines coming from the other three quadrants to complete the star-like pattern.

Option 4 matches this and completes the radial symmetry correctly.

Explanation

Option 4.

Explanation:  

The square is divided into four parts.

The top-right and bottom-left parts already have matching vertical and horizontal lines.

To complete the symmetry and pattern, the missing piece in the bottom-right (marked as X) must mirror the top-left.

Option 4 completes this symmetry correctly.

Explanation

 Option A (1) because:

- The pattern shows rotational symmetry.

- Each small triangle in the corners has a curved black design.

- The arrows in the missing quadrant (X) should continue the circular pattern.

Option 1 fits both the corner design and the arrow direction perfectly. Option 4 does not align with the arrow flow or corner pattern.

Explanation

• Option 1:

  • Top two arrows: SW (down-left)
  • Bottom two arrows: NW (up-left)
  • This matches our derived pattern for BR (arrows pointing left).

• Option 2:

  • Top two arrows: SE (down-right)
  • Bottom two arrows: NE (up-right)
  • This is the pattern for arrows pointing right (like TL and BL).

• Option 3:

  • Top two arrows: NW (up-left)
  • Bottom two arrows: SW (down-left)
  • The vertical direction of the arrows is inconsistent with the established pattern (top arrows generally have a downward component, bottom arrows an upward component).

• Option 4:

  • Top two arrows: NE (up-right)
  • Bottom two arrows: SE (down-right)
  • Similar to Option 3, the vertical direction is inconsistent.

Therefore, Option 1 is the correct figure to complete the pattern. The overall pattern for the horizontal direction of arrows in the quadrants is:

Explanation

ook closely at the figure “X”. It's divided into 4 quadrants.

The missing piece in the top-right corner should complete the symmetry based on the other three quadrants.

Option 2 is the only one that aligns properly with the triangular and line patterns to maintain that symmetry.

Explanation

Option 2 (B): The shape is rotated incorrectly (e.g., 180° instead of 90°).

Option 3 (C): The shape is close but may have a minor inconsistency (e.g., wrong size or orientation).

Option 4 (D): The shape fits perfectly, completing the 270° rotation (or full cycle) of the original shape.

Conclusion:

Option 4 (D) is correct because it adheres to the rotational pattern.

The other options are incorrect because they violate the rotational sequence or introduce inconsistencies.

Explanation

A hexagon is a polygon with 6 sides.

It has 6 angles, one at each vertex.

It also has 6 vertices.

Explanation

Inverse Proportion:

When one quantity increases, the other decreases in such a way that their product remains constant.

Example: Speed increases → Time to cover the same distance decreases.

Direct Proportion:

When one quantity increases, the other also increases at the same rate.

Example: More hours worked → More wages earned.

Explanation

Step 1: Assume original price = 100

(This makes percentage calculations easy)

Step 2: Increase by 20%

Step 3: Apply 25% discount on new price

Step 4: Find net change

Original price = 100
Final price = 90

Change = 90 − 100 = −10

Step 5: Percentage change
