Question 29
A company is releasing 12,000 biodegradable balloons into the sky as part of a global environmental awareness campaign. Over time, these balloons will fall back down to Earth. However, due to wind patterns, only 30% of the Earth's surface is expected to cause the balloons to land on land, while the remaining 70% will land in water. How many balloons must fall in total in order for exactly 100 of them to land on land instead of water?
