Answer:
11/6 days ( 2 Days)
Step-by-step explanation:
Two content Managers can complete developing questions for a module in 18
days.
=> one manager will take 18 * 2 = 36 Days to complete module
=> one manger one day work = 1/36
Work done in 7 Days = 7/18
Remaining work = 1 - 7/18 = 11/18
10 Interns join so total Man power available = 2 + 10 = 12
12 People one day work = 12 * 1/36 = 1/3
Number of days required = (11/18)/(1/3) = 11/6 ≈ 2 Days
