Test the divisibility of the folowing numbers by 10 :
(i) 5790 (ii) 63215 (iii) 55555

Answer

To test the divisibility of the given numbers by 10, we need to follow a simple rule: a number is divisible by 10 if its last digit is 0. Let's apply this rule to each of the numbers provided.

### Step-by-Step Solution:

1. **Check the first number: 5790**
- Look at the last digit of 5790, which is **0**.
- Since the last digit is 0, we conclude that **5790 is divisible by 10**.

2. **Check the second number: 63215**
- Look at the last digit of 63215, which is **5**.
- Since the last digit is not 0, we conclude that **63215 is not divisible by 10**.

3. **Check the third number: 55555**
- Look at the last digit of 55555, which is **5**.
- Since the last digit is not 0, we conclude that **55555 is not divisible by 10**.

### Final Results:
- **5790**: Divisible by 10
- **63215**: Not divisible by 10
- **55555**: Not divisible by 10
