| Village/Year | 2018 | 2019 | 2020 | 2021 |
| A | 12381 | 12800 | 13045 | 13256 |
| B | 10089 | 11478 | 11502 | 11931 |
| C | 7896 | 7942 | 8069 | 8275 |
| D | 5152 | 5230 | 5346 | 5500 |
What is the average population of village D during all 4 years?
Option 1: 5295
Option 2: 5300
Option 3: 5307
Option 4: 5315
Correct Answer: 5307
Solution :
The population of village D in the year 2018 = 5152
The population of village D in the year 2019 = 5230
The population of village D in the year 2020 = 5346
The population of village D in the year 2021 = 5500
Total population in 4 years = (5152 + 5230 + 5346 + 5500) = 21,228
$\therefore$ Average = $\frac{\text{Total population}}{\text{Number of years}}=\frac{21228}{4}= 5307$
Hence, the correct answer is 5307.
