In a certain code language, 'PROCTOR' is written as 'RUSBURW'. How wi…

1   2    3    4   5    6   7     8    9  10  11  12  13

The logic here is;

(the 1st letter is iinterchanged with 3rd, 3rd with 1st and 5th with 7th, 7th with 5th)

P +3 S

R +3 U

O +3 R

C +3 F

T +3 W

O +3 R

R +3 U

Similarly,

H +3 K

O +3 R

S +3  V

T +3 S

I +3 L

N +3 Q

G +3 J

Thus, VRKSJQL is correct.
