In a certain code language '526' means 'sky is blue', '24' means 'blue colour' and '436' means 'colour is fun'. Which of the following digit stands for 'fun'?

Options

A. 5
B. 4
C. 3
D. 2

Explanation

To solve the problem, we need to analyze the given coded messages and find out which digit corresponds to the word "fun." Let's break it down step by step.

### Step 1: Analyze the coded messages
We have three coded messages:
1. '526' means 'sky is blue'
2. '24' means 'blue colour'
3. '436' means 'colour is fun'

### Step 2: Identify common words and digits
- From the first coded message ('526' = 'sky is blue'), we see that the word "blue" appears in both the first and second messages.
- From the second coded message ('24' = 'blue colour'), we can deduce that "blue" must correspond to the digit '2' since it is the only digit in the second message.
- Therefore, "colour" must correspond to the digit '4' in the second coded message.

### Step 3: Compare the third coded message
Now, let's look at the third coded message ('436' = 'colour is fun'):
- We already established that "colour" corresponds to the digit '4'.
- This means that the remaining digits in '436' are '3' and '6', which correspond to the words "is" and "fun."

### Step 4: Determine which digit corresponds to "fun"
- Since we know that '6' corresponds to "blue" from the first coded message and '4' corresponds to "colour," we can deduce that '3' must correspond to "is."
- Therefore, the only digit left, which corresponds to "fun," is '6'.

### Conclusion
Thus, the digit that stands for "fun" is '3'.
