[tex]\rm m_d=200g[/tex]
[tex]\rm c=1\%[/tex]
[tex]\rm m_{apa}=?[/tex]
[tex]\rm m_s=?[/tex]
[tex]\boxed{\bf c=\dfrac{m_d}{m_s}\cdot100}[/tex]
[tex]\bf m_s=m_d+m_{apa}[/tex]
[tex]\rm m_s=\dfrac{m_d\cdot100}{c}=\dfrac{200g\cdot100}{1}=20000g=\bf20kg[/tex]
[tex]\rm m_{apa}=m_s-m_d=20000g-200g=19800g=\bf19,8kg[/tex]
