If SUMMER is coded RUNNER, the code for WINTER is

Let's break down this Coding and Decoding question step by step.

The question gives us a coded word: SUMMER is coded as RUNNER.
We need to find the code for WINTER using the same rule.

Let's compare SUMMER and RUNNER letter by letter to find the pattern:

S U M M E R
R U N N E R

1. Look at the first letter:
In SUMMER, the first letter is S.
In RUNNER, the first letter is R.
If you go one letter back in the alphabet from S, you get R. (S - 1 = R)

2. Look at the second letter:
In SUMMER, the second letter is U.
In RUNNER, the second letter is U.
The letter U remains unchanged.

3. Look at the third letter:
In SUMMER, the third letter is M.
In RUNNER, the third letter is N.
If you go one letter forward in the alphabet from M, you get N. (M + 1 = N)

4. Look at the fourth letter:
In SUMMER, the fourth letter is M.
In RUNNER, the fourth letter is N.
Again, the letter M changes to N. (M + 1 = N)

5. Look at the fifth letter:
In SUMMER, the fifth letter is E.
In RUNNER, the fifth letter is E.
The letter E remains unchanged.

6. Look at the sixth letter:
In SUMMER, the sixth letter is R.
In RUNNER, the sixth letter is R.
The letter R remains unchanged.

So, the rule for coding is:
1st letter: -1 (go one letter back)
2nd letter: No change
3rd letter: +1 (go one letter forward)
4th letter: +1 (go one letter forward)
5th letter: No change
6th letter: No change

Now let's apply this same rule to the word WINTER:

1. W (1st letter): Apply -1 rule. W - 1 = V
2. I (2nd letter): Apply no change rule. I = I
3. N (3rd letter): Apply +1 rule. N + 1 = O
4. T (4th letter): Apply +1 rule. T + 1 = U
5. E (5th letter): Apply no change rule. E = E
6. R (6th letter): Apply no change rule. R = R

Combining these letters, the code for WINTER is VIOUER.

Let's check the options:
Option A: SUITER
Option B: VIOUER
Option C: WALKER
Option D: SUFFER

Our calculated code VIOUER matches Option B.

Therefore, the correct answer is Option B: VIOUER.
