Population of Agra and Aligarh districts in the year 2001 was 36,20, 436 and 29,92,286, respectively. What was the total population of the two districts in that year?

Answer

To find the total population of the Agra and Aligarh districts in the year 2001, we will follow these steps:

### Step 1: Write down the populations of both districts.
- Population of Agra district in 2001 = 36,20,436
- Population of Aligarh district in 2001 = 29,92,286

### Step 2: Set up the addition of both populations.
We need to add the two populations together:
\[ \text{Total Population} = \text{Population of Agra} + \text{Population of Aligarh} \]
\[ \text{Total Population} = 36,20,436 + 29,92,286 \]

### Step 3: Perform the addition.
Let's add the numbers step by step:
```
36,20,436
+ 29,92,286
-------------
```
Starting from the rightmost digit:
- 6 + 6 = 12 (write 2, carry over 1)
- 3 + 8 + 1 (carry) = 12 (write 2, carry over 1)
- 4 + 2 + 1 (carry) = 7 (write 7)
- 0 + 9 = 9 (write 9)
- 2 + 2 = 4 (write 4)
- 6 + 9 = 15 (write 5, carry over 1)
- 3 + 2 + 1 (carry) = 6 (write 6)

So, the total population is:
```
36,20,436
+ 29,92,286
-------------
66,12,722
```

### Step 4: Write down the final answer.
The total population of Agra and Aligarh districts in the year 2001 was **66,12,722**.
