Explanation Correct Answer D

Explanation Correct Answer is B

Explanation Correct Answer B

Explanation The correct answer is D.

Explanation Option D

Explanation The square is rotating 45° clockwise each step Next rotated version matches option D

Explanation 1. Number of Parallelograms in a 2×3 grid Formula: Total = (m(m+1)/2) × (n(n+1)/2) = (2×3/2) × (3×4/2) = 3 × 6 = 18 Answer: 18 (not in options, closest is 16)

Explanation Based on the predictions: Circle: Top Left Large Triangle: White (Unfilled) Small Triangle: Right A (Circle: Top Left, Large Triangle: White, Small Triangle: Right) - Correct.

Explanation option 2 correct

Explanation f the ratio of Cost Price (CP) to Selling Price (SP) is 4:5, it means: - CP = 4 units - SP = 5 units Profit = SP − CP = 5 − 4 = 1 unit Profit % = (Profit / CP) × 100 = (1 / 4) × 100 = 25%

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 th e 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 The series follows the pattern of skipping one letter in the alphabet. Starting with A, the next letter skipped is B, resulting in C. Following this pattern, skipping one letter after each letter , the next letter after G would be I.

Explanation = 10*48*3 = 1440

Explanation What is the missing number? a triangle is a three-sided polygon that consists of three edges and three vertices. The rectangle is a quadrilateral shape ( 4-sided shape ) In geometry, a hexagon is a six-sided polygon ND-6-09-2023

Explanation Given: Profit = Rs. 120 Profit = 20% of Selling Price (SP) 20% of SP = 120 SP = 120 × 100/20 ​ = R s .600 Now, CP = SP − P ro f i t = 600 − 120 = R s .480

Explanation Cost Price (CP) = Rs. 800 Selling Price (SP) = Rs. 1,000 Gain = SP − CP = 1000 − 800 = 200 Gain % = (Gain ÷ CP) × 100 = 200/ 800 ​ × 100 = 25%

Explanation Original salary = Rs. 50,000 Increase = 20% of 50,000 20/100 ​ × 50 , 000 = 10 , 000 New salary: 50 , 000 + 10 , 000 = 60 , 000
