Answer:
90/17
Step-by-step explanation:
Ram can complete the work in (10 x 9) hrs = 90 hrs
Shyam can complete the work in (8 x 10) hrs=80 hrs
Therefore, Ram's 1 hour work=1/90 and Shyam's 1 hour work= 1/80
(Ram+Shyam)'s 1 hour's work =(1/90) + (1/80) = 17/720. So both Ram and Shyam will finish the work in 720/17 hrs
Therefore, Number of days of 8 hours each = (720/17) x (1/8) = 90/17
