Given : 4 workers complete the job at equal rates.
Due to a problem, two of the workers quit after working for only one day. The remaining two workers completed the job but required 4 more days than it was originally scheduled.
To Find : How many days was the job scheduled for?
Solution:
job scheduled for x days
Number of workers = 4
Total work = 4x man days
2 workers worked for 1 day
remaining 2 workers worked for x + 4 days
Hence Total work Done = 2 *1 + 2 * ( x + 4)
= 2x + 10 Man days
Equate
4x = 2x + 10
=> 2x = 10
=> x = 5
Hence originally scheduled for 5 days
