Find which of the following numbers are divisible by 10 :
(i) 5100 (ii) 4612
(iii) 3400 (iv) 8399

Answer

To determine which of the given numbers are divisible by 10, we need to check the last digit of each number. A number is divisible by 10 if its last digit is 0.

Let's analyze each number step by step:

1. **Check the first number: 5100**
- The last digit is **0**.
- Since the last digit is 0, **5100 is divisible by 10**.

2. **Check the second number: 4612**
- The last digit is **2**.
- Since the last digit is not 0, **4612 is not divisible by 10**.

3. **Check the third number: 3400**
- The last digit is **0**.
- Since the last digit is 0, **3400 is divisible by 10**.

4. **Check the fourth number: 8399**
- The last digit is **9**.
- Since the last digit is not 0, **8399 is not divisible by 10**.

Now, we can summarize our findings:

- The numbers that are divisible by 10 are **5100** and **3400**.
- The numbers that are not divisible by 10 are **4612** and **8399**.

### Final Answer:
The numbers divisible by 10 are: **5100 and 3400**.
