Answer 1

The Correct Option is C

By analyzing the given codes: - '786' means Study very hard, where '7' corresponds to Study, '8' to very, and '6' to hard.
- '958' means Hard work pays, where '9' corresponds to hard, '5' to work, and '8' to pays.
- '645' means Study and work, where '6' corresponds to Study, '4' to and, and '5' to work.
From this, we can conclude that the code for 'very' is '7'.
Thus, the correct answer is 7.

Answer 2

We are given the following codes and their meanings:

1. '786' means "Study very hard"
2. '958' means "Hard work pays"
3. '645' means "Study and work"

Step 1: Identify common words and codes:
- The word "Study" appears in phrases 1 and 3.
- The common digit in codes '786' and '645' is '6' (since 7,8 are unique to '786', and 4,5 are unique to '645').
Thus, '6' likely corresponds to "Study".

Step 2: Identify code for "Hard":
- "Hard" appears in phrases 1 and 2.
- The common digit in codes '786' and '958' is '8'.
So, '8' corresponds to "Hard".

Step 3: Identify code for "Work":
- "Work" appears in phrases 2 and 3.
- The common digit in codes '958' and '645' is '5'.
So, '5' corresponds to "Work".

Step 4: Identify code for "Very":
- The remaining digit in '786' after excluding '6' (Study) and '8' (Hard) is '7'.
- The word "Very" is in phrase 1 but not in phrases 2 or 3.
Therefore, '7' corresponds to "Very".

Final Answer:
The code for "very" is 7.
