Doubt (Question: 179728.0 )

Sir, How can you say that further, they will take 5 hours to complete the work? Because it didn't mention in the question

Question:

Two workers undertake to do a job. The second worker started working 2 hours after the first. Five hours after the second worker has begun working there is still 9/20 of the work to be done. When the assignment is completed, it turns out that first worker has done 60% of the work, while second worker has done rest of the work. How many hours would take each one to do the whole job individually?

Options:
A) 10 hours and 12 hours   
B) 15 hours and 10 hours
C) 20 hours and 25 hours 
D) 18 hours and 20 hours
