In a certain coding language, if the word 'STORK' is coded as 'VQRON', then the word 'TIRED' will be coded as:

AV E T C F

BW F U B G ✓ Correct

CW E T C G

DV F U B F

Correct answer: (B) W F U B G

Explanation

TIRED becomes W F U B G under the alternating shift of the code.

STORK to VQRON shows letters move +3, -3, +3, -3, +3 in turn.

Applying this, T+3 is W and I-3 is F.

Then R+3 is U, E-3 is B and D+3 is G.

The pattern of adding and subtracting three gives WFUBG.
