In a code language, ‘ROAD’ is written as ‘QKZZ’, and ‘BAND’ is written as ‘AWMZ’. How will ‘TASK’ be written in that language?

The correct option is SWRG.

To find how the word ‘TASK’ is coded, let us first analyze the relationship between the letters in the given examples: ‘ROAD’ → ‘QKZZ’ and ‘BAND’ → ‘AWMZ’.

We can determine the pattern by looking at the positions of the letters in the English alphabet (A = 1, B = 2, ..., Z = 26):

Case 1: ROAD → QKZZ
R (18) − 1 = Q (17)
O (15) − 4 = K (11)
A (1) − 1 = Z (26) (Wrapping around the alphabet)
D (4) − 4 = Z (26) (Wrapping around the alphabet)

Case 2: BAND → AWMZ
B (2) − 1 = A (1)
A (1) − 4 = W (23)
N (14) − 1 = M (13)
D (4) − 4 = Z (26)

From the above examples, we can see that the pattern is to subtract 1 and 4 alternately from the alphabetical positions of the letters: −1, −4, −1, −4.

Now, let us apply this pattern to the word TASK:
T (20) − 1 = S (19)
A (1) − 4 = W (23)
S (19) − 1 = R (18)
K (11) − 4 = G (7)

Thus, ‘TASK’ is coded as SWRG.
