//Declaration of Variables
v0 = 25 // ml, sewage
d0 = 410 // ppm, dissolved oxygen
d1 = 120 // ppm, dissolved oxygen
v1 = 50 // ml, sewage
// Solution
mprintf("BOD = (DOb - DOi) * Dilution Factor\n")
mprintf(" BOD = (DOb - DOi) * (ml of sample after dilution) / (ml of sample before dilution)\n")
BOD = (d0 - d1) * (v1 / v0)
mprintf(" BOD = %d ppm",BOD)
