Solid waste generated from an industry contains only two components, X and Y as shown in the table belowComponent Composition Density (% weight) (kg/m3)X c1 ρ1Y c2 ρ2Assuming (c1 + c2) = 100, the composite density of the solid waste (ρ) is given by:

• A. \(\frac{{100}}{{\left( {\frac{{{c_1}}}{{{\rho _1}}} + \frac{{{c_2}}}{{{\rho _2}}}} \right)}}\)
• B. \(100\left( {\frac{{{\rho _1}}}{{{c_1}}} + \frac{{{\rho _2}}}{{{c_2}}}} \right)\)
• C. \(100\left( {{c_1}{\rho _1} + {c_2}{\rho _2}} \right)\)
• D. \(100\left( {\frac{{{\rho _1}{\rho _2}}}{{{c_1}{\rho _1} + {c_2}{\rho _2}}}} \right)\)
