Correct Answer

Explanation

Based on the information given, it can be calculated that C's individual contribution to completing the job in one day is equal to the total work done by A, B, and C in one day minus the total work done by A and B in one day.
If we let "x" represent the amount of work that C can do in one day, then the equation would be:v x = (A+B+C)'s one day work - (A+B)'s one day work
Using the information provided, we can substitute the values and solve for x:
x = (Apti Time and work 52) - (Apti Time and work 51)
x = Apti Time and work 53
Therefore, C can complete the job in 15 days if they work individually at a rate of Apti Time and work 53 per day.
