Explanation:
- Start with a village population of 1,000 people.
- In the first year, the population increases by 10%.
- Calculate 10% of 1,000: 0.10 x 1,000 = 100.
- New population after the increase: 1,000 + 100 = 1,100.
- In the second year, the population decreases by 10%.
- Calculate 10% of 1,100: 0.10 x 1,100 = 110.
- New population after the decrease: 1,100 - 110 = 990.
- The options are:
- Option 1: 985
- Option 2: 980
- Option 3: 990
- Option 4: 995
- Correct Answer: Option 3 - 990.
