The population of Karnataka, Delhi and Gujarat are respectively `54,37,211, 7,64,46,300 and 12,43,998`. What is combined population of the three states?

Answer

To find the combined population of Karnataka, Delhi, and Gujarat, we will add the populations of each state step by step.

### Step 1: Write down the populations
- Population of Karnataka: 54,37,211
- Population of Delhi: 7,64,46,300
- Population of Gujarat: 12,43,998

### Step 2: Align the numbers for addition
We will align the numbers based on their place values (crores, lakhs, thousands, hundreds, tens, and units):

```
7,64,46,300 (Delhi)
+ 54,37,211 (Karnataka)
+ 12,43,998 (Gujarat)
```

### Step 3: Add the populations
We will add the numbers column by column starting from the rightmost side (units place):

1. **Units place**: 0 + 1 + 8 = 9
2. **Tens place**: 0 + 1 + 9 = 10 (write down 0 and carry over 1)
3. **Hundreds place**: 3 + 2 + 4 + 1 (carry) = 10 (write down 0 and carry over 1)
4. **Thousands place**: 6 + 7 + 3 + 1 (carry) = 17 (write down 7 and carry over 1)
5. **Lakhs place**: 4 + 4 + 4 + 1 (carry) = 13 (write down 3 and carry over 1)
6. **Crores place**: 7 + 5 + 0 + 1 (carry) = 13 (write down 3 and carry over 1)

So, the combined population is:

```
8,31,27,509
```

### Final Answer
The combined population of Karnataka, Delhi, and Gujarat is **8,31,27,509**.
