The correct mirror image of the given figure when the mirror is placed at AB is shown below:

Hence, 'option 3' is the correct answer.

According to the given statement: Rogerio, in search of an internet café, walked 30 m due North.

He turned right and walked 18 m.

He again turned right and walked 30 m.

Finally, he turned left and walked 22 m to reach the internet café.

Distance between Starting point and Final Point : 18m + 22m = 40m.

So, the Internet cafe is 40m in the East Direction from the starting point.

Hence, the correct answer is 'Option 4'.

The figure that will replace the question mark (?) in the following figure series is shown below:

Hence, the correct answer is "Option 2".

The Pattern followed here is;

Hence, the correct answer is "206".

Given : Seven people, A, B, C, D, E, F and G are sitting in a straight row, facing north.

Explanation : 

1) A sits second from the left.

2) Only two people sit between A and C.

3) Only three people sit between D and F and D is an immediate neighbour of A.

4) B is an immediate neighbour of D and E is not an immediate neighbour of C.

After positioning E and B only one position is left which will be occupied by the only person left i.e G.

Thus, according to the final arrangement E sits to the extreme left.

Hence, "E" is the correct answer.

The positional value of the letter of the alphabet series:

The logic followed here is shown below;

WKDL : XIGH

Hence, the correct answer is "Option 3)".

The logic followed in the given figure series is:

From Figure (1) to (2):

The symbols move as shown below.

From Figure (3) to (4):

The symbols move as shown below.

Hence, the correct answer is "Option (2)".

The logic followed here is :-

'GINGER' is coded as LZCKGF.

and

'GARLIC' is coded as WDHOYF.

Hence, the correct answer is "MZRLJB".

The pattern followed here is,

Hence, the correct answer is "CDFI".

The logic is:

Needle : Sew → Sewing is done using a needle and a thread.

Similarly,

Auger : ? → Boring i.e, making a long deep hole is done using an auger.

Hence, Bore is the correct answer.
