Solution:

24

Explanation:
There are a total of 24 triangles in the given figure.

To make it easy to understand, we have put numbers on each distinct triangle. So let us start counting them now.
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, (1+2), (1+2), (1+2+3), (1+2+3+4), (2+3), (2+3+4), (3+4), (5+6), (5+6+7+8), (7+8), (1+2+5+6), (3+4+7+8), (2+6+9), (3+7+10), (6+9), (7+10) and (6+7+9+10).

Solution:

This open figure will result in the cube given in the option C.

Solution:

First climb the first rope and carry the end of the second one with you. Now cut the first rope and flush with the ceiling, then swing down on the second. This time, climb up the second and cut that flush with the ceiling as well but only part way till it can withstand your weight. Now slowly climb down till you're just short of the bottom. Now tie a tiny loop at this portion and climb up some two feet. Then secure the loop about your feet and jump to the ground. With a three feet fall, you won't be hurt but the force will snap off the rope at top and you will have the whole rope with you.

Solution:

The missing tile will be 3.

Explanation:
0 + 0 = 0
1 + 2 = 3
0 + 2 + 2
1 + 4 = 5
3 + 1 = 4
6 + 1 = 7
3 + 3 = 6
6 + 3 = 9

If you see the patter, with each pair the total sum is increasing by three and then decreasing by 1. Therefore the missing tile will be 3.

Solution:

Now you must be aware of the fact that in general, the magnetic field is present only on the poles of the magnet. Thus keep any rod on a surface. Then hold the other rod in your hand and bring its tip close to the center of the rod that is lying down on the surface. If the rod comes close to the rod you are holding, then the one you are holding is a magnet. However, if the rod does not gets attracted towards your rod, then the one that is lying is the magnet.

Solution:

Q

Explanation:
First Square:
6 + 4 + 4 = 14
N is the 14th letter.

Second Square:
4 + 1 + 7 = 12
L is the 12th letter.

Third Square:
5 + 6 + 10 = 21
U is the 21st letter.

Fourth Square:
14 + 2 + 1 = 17
