a can do a piece of work in 8 days . b can do it in 6 days . with the assistance of c they completed the work in 2 days . find in how many days can c alone do it ?
"c = 1 / 2 - 1 / 8 - 1 / 8 = 5 / 24 = > 4.8 days answer : e"
divide(multiply(8, 6), divide(subtract(multiply(8, 6), multiply(add(divide(multiply(8, 6), 8), divide(multiply(8, 6), 6)), 2)), 2))
