A is the correct version of C. According to the shape of the figure, the building (say) has a top landing with side walls. So, the strip should be as shown in A rather than being continuous on the top as shown in C.
B and D are correct.

32) D

Observe each column. From top to bottom in each column, the no. of sides of the polygon (geometry shape) increases by one and all the shapes has the same color. Say in the first column, triangle = 3 sides, square = 4 sides, pentagon = 5 sides
second column, the no of sides from top to bottm are: 5, 6,7
So, in the third column also, the no. of sides of the shapes should be
So, D is the answer considering the color too.

Count the no. of alphabets in the given word, for example, sabarmati has 9 letters and hence 92, Hoogly has 6 letters and hence 62, you can check the rest too. Similarly, Narmada has 7 letters and hence it should start with 7. Again, regarding the second numeric of the number, it represents the no. of vowels in the given word, Sabarmati has 3 A's and 1 I, so 4 vowels and hence 94, Beas has two vowels and hence 42. Similarly, Narmada has 3 vowels and hence 73

JST is 3.30 hrs ahead of IST. It means if IST is say 12 JST will be 3.30.
Since Namit started by 12.20 pm from Delhi and the total travel time (adding 2 hr 15 min of layover) would be 12.20 + 9.45 + 2.15 = 24.20pm which is 00.20 AM in the next day morning in the standard IST. Adding 3.30 hrs, we have 00.20+3.30 = 3.50AM

47) A

Trying to solve it mathematically, the following explanation would work. Say the area is 144

circle area is PI*R^2 = 144, which says R = 6.7
Circle perimeter = 2 *PI*R = 2*3.14*6.7 = 42.1

Square area is A^2 = 144, which means A = 12
It's perimeter is 4A = 4*12 = 48

Equilateral triangle of side A is Sqrt(3)*A^2/8 = 144
A = 25.8
It's perimeter is 3A = 77.37

So,  circle < sqaure <perimeter.

48) A

Example, a circle swept in 3D would result into a sphere. I assume you can imagine the rest solids. Stability of the solid can be determined by keeping the solid on say a flat surface and by giving a slight disturbance to it.
A sphere is the most unstable solid for even a small disturbance would be enough to dispel its static position, next comes the egg shape (from ellipse), the cone is the most stable solid considering that the flat circular surface of it is on ground. So, the order should be (increasing order)

circle, ellipse, star, triangle

52) A

53) C

Note the number of sides of the shape including the number of partitions, for example, the first image has 5 sides and 2 partitions and hence 5*2 = 10
the second shape has 4 sides and 2 partitions and hence 4*2 = 8
the third has 6 sides and 4 partitions, hence 6*4 = 24
Finally, the fourth image has 6 sides and  3 partitions and hence 6*3 = 18

54) A

All the given views are eligible to have the same front and top view.

55) D

The given set of four patterns has the following common features
dark solid rectangles = 2
empty rectangles = 2
straight lines = 4

Based on the above observation, we can say that B is the correct choice
