A village uses 500 liters of water per day for irrigation. If the village area increases by 20% and water requirement rises proportionally, how many liters per day will the village need after expansion?

Step-by-step solution

1. Calculate 20% of 500 liters: $0.20\times 500=100$ liters.
2. Add the increase to the original amount: $500+100=600$ liters.
3. Conclude that the village will need 600 liters per day after expansion.
