In a certain code language PREMONITION is written as 68530492904 , how will the word MONITOR be written in that code language?

Option c: 3049208. Solution: This is a direct substitution code where each letter is assigned a specific digit: From PREMONITION o 68530492904 : - P → 6 - R → 8 - E → 5 - M → 3 - O → 0 - N → 4 - I → 9 - T → 2 Now, substitute the corresponding digits for each letter of the word MONITOR: - M → 3 - O → 0 - N → 4 - I → 9 - T → 2 - O → 0 - R → 8 Combining these digits, the code for MONITOR is 3049208 . Hence, Option C is the correct answer.

In a certain code language PREMONITION is written as $68530492904$, how will the word MONITOR be written in that code language?

The correct answer is Option c: $3049208$. This is a direct substitution code where each letter is assigned a specific digit: From **PREMONITION** $ o 68530492904$: - $\text{P} \to 6$ - $\text{R} \to 8$ - $\text{E} \to 5$ - $\text{M} \to 3$ - $\text{O} \to 0$ - $\text{N} \to 4$ - $\text{I} \to 9$ - $\text{T} \to 2$ Now, substitute the corresponding digits for each letter of the word **MONITOR**: - $\text{M} \to 3$ - $\text{O} \to 0$ - $\text{N} \to 4$ - $\text{I} \to 9$ - $\text{T} \to 2$ - $\text{O} \to 0$ - $\text{R} \to 8$ Combining these digits, the code for **MONITOR** is $3049208$. Hence, **Option C** is the correct answer.

B $\displaystyle 3029408$
C $\displaystyle 3049208$
D $\displaystyle 3049258$

Detailed Solution & Explanation

This is a direct substitution code where each letter is assigned a specific digit:
From **PREMONITION**

\displaystyle o 68530492904

:
-

\displaystyle \text{P} \to 6

\displaystyle \text{R} \to 8

\displaystyle \text{E} \to 5

\displaystyle \text{M} \to 3

\displaystyle \text{O} \to 0

\displaystyle \text{N} \to 4

\displaystyle \text{I} \to 9

\displaystyle \text{T} \to 2

Now, substitute the corresponding digits for each letter of the word **MONITOR**:
-

\displaystyle \text{M} \to 3

\displaystyle \text{O} \to 0

\displaystyle \text{N} \to 4

\displaystyle \text{I} \to 9

\displaystyle \text{T} \to 2

\displaystyle \text{O} \to 0

\displaystyle \text{R} \to 8

Combining these digits, the code for **MONITOR** is

\displaystyle 3049208

.

Hence, **Option C** is the correct answer.
