Let's we consider that the number of workers initially allocated to the project is 'a'. In one day, 'a' workers can complete 1/20th of the project. Then, due to unpredicted situation there will absence of 5 workers, the effective number of workers working on the project is (a - 5). Since the project got detained by 5 days, the entire number of days taken to complete the project is 20 + 5 = 25. Therefore, we can set up the equation to solve for 'a': (a- 5) x 25 = a x 20 25a - 125 = 20a 25a – 20a = 125 5a = 125 a = 125 / 5 a = 25 Therefore, the initial number of workers allocated to the project is 25.
