Given:
anna bought soil that contains 12% of water .
she wants to plant a flower that needs 18% of water .
To Find:
how much water does she need to pour in 5 kg of soil to plant the flower
Solution:
anna bought soil that contains 12% of water
5 kg of soil
=> Water = (12/100)2 = 0.6 kg
Let say Water poured = W kg or litre
Total Water = 0.6 + W kg
Total Soil = 5 + W kg
18% of water
=> (18/100)(5 + W) = 0.6 + W
=> 90 + 18W = 60 + 100W
=> 30 = 82W
=> W = 30/82
=> W = 0.366 kg or 0.366 litre
or 3.66 dl
3.66 dl water to be added
