150 workers were engaged to finish a job in a certain number of days. 4 workers dropped out on second day, 4 more workers dropped out on third day and so on. It took 8 more days to finish the work. Find the number of days in which the work was completed.
Let V be the number of days that the work was to be completed
∴ For one worker, number of days required to complete the work = 150n.
150 + 146 + 142 + ….upto (n + 8) terms = 150n.
