Total loss %=10+5=15%

CP=70000
loss%=15%

Now

Loss:-

$\\ \sf\longmapsto 15\%\:of\:70000$

$\\ \sf\longmapsto \dfrac{15}{100}(70000)$

$\\ \sf\longmapsto 10500$

Again

$\\ \sf\longmapsto SP=CP-Loss$

$\\ \sf\longmapsto SP=70000-10500$

$\\ \sf\longmapsto SP=59500$

\cfrac{6000~\underline{lbs}}{\underline{day}}\cdot \cfrac{ton}{2000~\underline{lbs}}\cdot \cfrac{7~\underline{day}}{week}\implies \cfrac{6000\cdot 7~ton}{2000~week}\implies 21.00\frac{ton}{week}$

$\bf -------------------------------\\\\
