We are to relate the two words "NATURAL" AND "UBOUMBS"
Original letters                    Change                     Encrypted letter
N                                              +7                                    U
A                                              +1                                    B
T                                              -5                                      O
U                                               0                                     U
R                                               -5                                    M
A                                               +1                                   B
L                                               +7                                     S

Pattern obtained = +7 +1 -5 0 -5 +1 +7
We have 4 sets of changes - +7,+1,-5,0 which are to be assigned a,b,c,d respectively.
So we take the word "PROBLEM"
if we encrypt the first letter in a similar pattern we will get 'W' which is not in any of the options.
Similarly, there is no change of -5
So we assign them to be either a or c
So we observe changes of +1 and 0 only
Now notice the change
1st and last letter of the encrypted "NATURAL" is encrypted in a same way, that is, +7 is added.
Hence from the four options, we clearly observe this change only in the first option.
Further on going through the pattern we will find a similar pattern as that of "NATURAL". Hence the answer is A. QSPBMFN




Let the initial Point be A So from the the car moves 20km north , taking it as B.From B it turned a sharp left and went 30km taking as C.From C another 20km was covered, taking it as D. And finally from D she turned left and covered 45km.
                                            30km
                               C                               B                                        
                      20km                                      20km      

                               D                                A
                                            45km

So if we observe closely, we would get a rectangle ABCD(BC=AD Since,opposite sides are equal in triangles)
Hence the distance from point D to A, that is, inital point is around 30km. 
So the car did not stop at the initial point, it went further to cover another (45-30)km that is , 15km. So at present the car must be 30km towards East from the Initial point

                                            30km

                               C                               B                                        

                      20km                                      20km      

                               D                                A
