Vedmedyk [2.9K]

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

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

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

$\\ \sf\longmapsto SP=59500$

Third farmer will pay 59500
