Answer» Answer: The original number of men is 40 Step-by-step explanation: LET there be x men originally. x men finish the work in 60 DAYS and (x+8) finish it in 50 days. x men finish the job in 60 days. 1 man can finish it in 60X days. (x+8) men can finish the job in 50 days. 1 man can finish it in 50(x+8) days. Therefore, 60x = 50(x+8) 60x = 50x+400 60x-50x = 400 10x = 400 x = 400/10 x = 40 So, the original number of men is 40 |
