Understanding the Letter Coding Rule

In this type of coding question, each letter in the original word is replaced by a specific letter according to a given rule or pattern. We need to first understand the mapping provided for each letter.

Decoding the Given Letter Mappings

The question provides the following specific coding rules:

• O is written as E
• A as C
• M as I
• S as O
• N as P
• E as M
• I as A
• P as N
• C as S

We can list these mappings clearly to make it easier to apply them to the word "COMPANIES".

Applying the Coding to "COMPANIES"

Now, we will take the word "COMPANIES" and replace each letter using the coding mapping we identified.

Let's go through each letter of "COMPANIES":

• C: According to the rule, C is written as S.
• O: According to the rule, O is written as E.
• M: According to the rule, M is written as I.
• P: According to the rule, P is written as N.
• A: According to the rule, A is written as C.
• N: According to the rule, N is written as P.
• I: According to the rule, I is written as A.
• E: According to the rule, E is written as M.
• S: According to the rule, S is written as O.

Forming the Coded Word

Combining the coded letters in order, we get:

S + E + I + N + C + P + A + M + O

This gives us the coded word SEINCPAMO.

Conclusion

Following the specific letter coding rules provided in the question, the word COMPANIES is written as SEINCPAMO in that code.
