Question

P can complete a task in ydays while Q takes y+12 days to do the same task. (a). What fraction of the task can each of them complete in a day?

Answer 1

P: fraction of task completed in one day = 1/y

Q: fraction of task completed in one day = 1/(y + 12)

 

Think of it with numbers. If I can complete a task in 5 days, that means each day I completed 1/5 of the task. After 5 days, i completed the entire task.
