In a certain code,
‘child plays game’ is coded as 'ra so tu'
‘adult plays work’ is coded as 'ke so mi'
‘game work activity’ is coded as 'tu mi lo'
Q. What is the code for activity?

The correct option/answer is lo.

To find the code for the word "activity", we can compare the given coded statements step-by-step to isolate the code for each word:
1. ‘child plays game’ is coded as 'ra so tu' (Statement 1)
2. ‘adult plays work’ is coded as 'ke so mi' (Statement 2)
3. ‘game work activity’ is coded as 'tu mi lo' (Statement 3)

Step 1: Find the code for "plays"
Comparing Statement 1 and Statement 2, the common word is "plays" and the common code code is "so".
Thus, "plays" = "so".

Step 2: Find the code for "game"
Comparing Statement 1 and Statement 3, the common word is "game" and the common code is "tu".
Thus, "game" = "tu".

Step 3: Find the code for "work"
Comparing Statement 2 and Statement 3, the common word is "work" and the common code is "mi".
Thus, "work" = "mi".

Step 4: Find the code for "activity"
Now, let us analyze Statement 3: ‘game work activity’ is coded as 'tu mi lo'.
We have already determined that "game" is coded as "tu" and "work" is coded as "mi".
By elimination, the remaining word "activity" must be represented by the remaining code, which is "lo".
