Q61.If A = {1,2,3,4,6} B= {2,4,5,7} then B-A =?
Correct Answer: D
B - A consists of elements in B that are not present in A. B - A = {5, 7}. Since this set is not listed, 'none' is the correct choice.
Q62.Which figure completes the horizontal reflection of the concentric triangles?
Correct Answer: B
A horizontal reflection mirrors the top half of the concentric triangles to the bottom half, and vice versa, which is represented by option B.
Q63.Which figure completes the analogy: Arrow pointing down rotates 90 degrees counter-clockwise to point right; so Arrow pointing up rotates to?
Correct Answer: D
A 90-degree counter-clockwise rotation applied to an upward-pointing arrow results in an arrow pointing to the left (D).
Q64.A man going to a mosque meets another man with his 7 spouses. Each spouse has a child in their arms. What is the total number of people going to mosque?
Correct Answer: C
Only the first man is stated to be 'going to' the mosque. The group he meets along the way are not stated to be heading to the mosque.
Q65.Arrange of country name Kistnap?
Correct Answer: A
The jumbled letters 'Kistnap' can be rearranged to form the country name 'Pakistan'.
Q66.There are 3 cows, 2 chickens and 6 cats: calculate the total legs for all?
Correct Answer: B
3 cows * 4 legs = 12; 2 chickens * 2 legs = 4; 6 cats * 4 legs = 24. Total legs = 12 + 4 + 24 = 40.
Q67.If Murshid is smaller than Azhar but taller than Ahmed, who is the tallest of the three?
Correct Answer: C
Since Murshid is taller than Ahmed but shorter than Azhar, the height order is Azhar > Murshid > Ahmed. Azhar is the tallest.
Q68.Five files—P, Q, R, S, and T—are placed in a drawer. R is above P, Q is below T, and S is above R but below T. Which file is at the top?
Correct Answer: B
Based on clues: T is above S, S is above R, R is above P, and Q is below T. The layout from top to bottom is T > S > R > P > Q. File T is at the top.
Q69.Select the correct option to complete the radial symmetry of lines radiating from the center of a 2x2 quadrant box.
Correct Answer: D
Option 4 correctly extends the radial symmetrical line pattern towards the center.
Q70.In a square divided into four parts, the top-right and bottom-left parts have matching vertical and horizontal lines. Which option completes the pattern for the missing bottom-right quadrant?
Correct Answer: D
Option 4 mirrors the top-left section, completing the horizontal-vertical line symmetry.
Q71.Which quadrant completes the rotational symmetry curved arrows in the corners?
Correct Answer: A
Option 1 fits the corner design and follows the clockwise arrow flow perfectly.
Q72.In a 2x2 grid of arrow directions, which quadrant completes the correct horizontal flow of arrows?
Correct Answer: A
Option 1 completes the pattern of SW (down-left) and NW (up-left) arrows correctly.
Q73.Which figure completes the triangular and line patterns inside quadrant box X?
Correct Answer: B
Option 2 aligns with the triangular diagonal flow, maintaining symmetry.
Q74.Which option completes the rotational sequence (270 degrees or full cycle) of the original shape?
Correct Answer: D
Option 4 continues the systematic clockwise rotation.
Q75.The difference of two positive integers is 3 and the sum of their squares is 89. The integers are?
Correct Answer: B
Let the numbers be x and y. x - y = 3 and x² + y² = 89. Solving gives (y+3)² + y² = 89 => 2y² + 6y - 80 = 0 => y = 5 and x = 8.
Q76.Which letter precedes the letter that comes after U?
Correct Answer: D
The letter that comes after U is V. The letter that precedes V is U itself.
Q77.If LIVE is coded as EVIL, then 52324 is coded as?
Correct Answer: C
LIVE reversed is EVIL. Reversing the digits of 52324 yields 42325.
Q78.Identify the total number of blocks/cubes in the given stair structure.
Correct Answer: C
There are 6 visible cubes and 4 hidden cubes supporting the structure. Total = 10 cubes.
Q79.Identify the figure that completes the pattern of overlapping geometric shapes with diagonal crosses.
Correct Answer: C
Option 3 aligns with the symmetry and rotation pattern established by the other three quadrants.
Q80.Which quadrant completes the intersecting curved lines pattern to ensure visual balance?
Correct Answer: C
Option 3 has curved lines that properly align and complete the flow from adjacent quadrants.
