Answer:
Adam can finish the work in 15 days.
Therefore, Adam’s 1 day’s work = 1/15
Brandon can finish the work in 10 days.
Therefore, Brandon’s 1 day’s work = 1/10
So, (Adam + Brandon)‘s 1 day’s work = 1/15 + 1/10 = (2 + 3)/30 = 5/30 = 1/6
Therefore, (Adam + Brandon)‘s 5 day’s work = 5 × 1/6 = 5/6
Remaining work = 1 – 5/6 = 6-5/6 = 1/6
This remaining work has to be done by Brandon.
Complete work is done by Brandon in 10 days.
Therefore, 1/6 of the work is done by Brandon in (10 × 1/6) days = 5/3 days.
Hence, the remaining work is done by Brandon in 5/3 days.
