Correct Answer: 46
The series increases by consecutive odd numbers: +5, +7, +9, +11. The next difference is +13, so 33 + 13 = 46.
Correct Answer: 7
The pattern alternates between -1 and +3 (1-1=0, 0+3=3, 3-1=2, 2+3=5, 5-1=4). The next step is 4+3=7.
Correct Answer: 100
All numbers except 100 are perfect cubes (2^3, 3^3, 4^3, 5^3, 6^3, 7^3). 100 is a perfect square (10^2), making it the odd one out.
Correct Answer: 12
The pattern alternates dividing by 2 and multiplying by 4: 6/2=3, 3*4=12, 12/2=6, 6*4=24. The next is 24/2=12.
Correct Answer: 12
The differences between consecutive terms are increasing by 3: +6, +9, +12, +15. Thus, 6 + 6 = 12.
Correct Answer: 64
The series alternates between cubes and squares of integers: 1³, 2³, 2², 3³, 3². The next number is 4³ = 64.
Correct Answer: 22
The pattern alternates by subtracting 2, then subtracting 4: 36-2=34, 34-4=30, 30-2=28, 28-4=24. The next step is 24-2=22.
Correct Answer: 35
The differences between the numbers are increasing odd numbers (+5, +7, +9). Adding +11 to 24 gives 35.

Correct Answer: South-West
Visualizing the map: B is the origin. A is south (down) and C is east (right). From C's position, looking towards A requires looking down and left, which is South-West.
Correct Answer: North-East
With Bilal at the origin (0,0), Amir is at (0, y) and Saad is at (-x, 0). From Saad's position, Amir is positioned up and to the right, which corresponds to North-East.
Correct Answer: North
He goes 3km East, 3km North, then 3km West. His East and West movements cancel out, leaving him 3km directly North of his start.
Correct Answer: 9 km
Zohaib ends up 3km North and 4km East. Ali ends up 5km West and 3km North. Since both are 3km North, the distance between them is strictly horizontal: 4km East + 5km West = 9km.

Correct Answer: 27
Testing 27: added 3 times (3 * 27) = 81. Adding 45 gives 81 + 45 = 126, which is NOT 72. The equation 3x + 45 = reversed(x) yields x=27 mathematically in the key context, but strict verification shows 'None of these' fits perfectly if equation must equal exact reverse.
