hello folks

i totaly agree that the total number spend on this work is 10 days. but i have a question regarding the way the question is ask. it is asking 'In how many days did the work get over from the time John and Jane started to work on it together?'. i feel like from the time they start work together it is 6 not 10 cuz john start alone. please can you explain me why it is 10. please somebody to respond to me

The question tells us: "John and Jane set out to complete the task by beginning to work together. However, Jane was indisposed 4 days before the work got over."

So they started working together and John completed it at the end. It took 10 days to complete.

It asks: "In how many days did the work get over from the time John and Jane started to work on it together"

From the time they started, how many days did it take to finish the work? From the time they started, it tool 10 days. Who worked for how many days doesn't matter. The work took 10 days to complete.
