28 men can finish the job in 60 days. At the start of the 16 day, 5 men were laid off and after the 45th, 10 more men were hired. How many days were delayed in finishing the job? Please explain, step by step.
let eaceh man do x amount of work. so the total amount of work to be done is 28*x*60=1680x work done in first 15 days = 28*x*15 =420x work done in the next 30 days =23*x*30=690x remaining work = 1680-690-420=570x so remaining days = 570x/33x=17.27 so total days are 62.27 2.27 days excess
a repeat yes?
