In a store window, there was a box of berries having a total weight of 200 kg.  The berries were 99% water, by weight.  After two days in the sun, the water content of the berries was only 90%, by weight.  What was the total weight of the berries after two days, in kg?

Hello Guest!

 

\(m_b:1\%=200kg:100\%\\ \underline{m_b=2kg}\\ x:m_b=100\%:10\%\\ x:2kg=100\%:10\%\\ \color{blue}x=20kg \)

20kg was the total weight of the berries after two days.
