Elitmus Exam Numerical Ability Quadratic Equations

Some men do a work, at the end of day one man leaves, when the last man leaves the work is completed,In how many days can one man do the work if the work is done otherwise in 0.6 Time

Read Solution (Total 1)

no, the work can't be completed.. as a man keeps walking out at the end of the work gets increased...
EX: 10 man can do in 10 day.. so 100 parts to be completed in 10 days..
1st day--- 10 and 1 man left
now 2nd day.. 100-10=90; 9 men..and work done is 9 and 90-9=81
3rd days... last day ... one man will le walked out so 8.. 81-8=73
if this process is keep on repeating..the work will not be completed
