In a certain code EAT is written as 318 and CHAIR is written as 24156. What will TEACHER be written as?

Options

A. 8312346
B. 8321436
C. 8312436
D. 8313426

Explanation

To solve the problem, we need to decode the letters based on the given codes for the words "EAT" and "CHAIR".

### Step-by-Step Solution:

1. **Identify the codes for the letters in "EAT":**
- EAT is coded as 318.
- From this, we can deduce:
- E = 3
- A = 1
- T = 8

2. **Identify the codes for the letters in "CHAIR":**
- CHAIR is coded as 24156.
- From this, we can deduce:
- C = 2
- H = 4
- A = 1 (already known)
- I = 5
- R = 6

3. **Compile the codes for each letter:**
- E = 3
- A = 1
- T = 8
- C = 2
- H = 4
- I = 5
- R = 6

4. **Now, we need to find the code for "TEACHER":**
- T = 8
- E = 3
- A = 1
- C = 2
- H = 4
- E = 3 (again)
- R = 6

5. **Combine the codes for "TEACHER":**
- Therefore, TEACHER will be coded as:
- T (8), E (3), A (1), C (2), H (4), E (3), R (6)
- This results in the code: **8312436**

### Final Answer:
TEACHER will be written as **8312436**.
