A two storey building is to be completed in 48 days. To meet the deadline 54 men were employed and were made to work for 10 hours a day. After 30 days 5/9th of the work was completed. How many more workers should be employed to meet the deadline if each workers are now made to work 8 hours a day?
54 men work 10 hours a day for 30 days and 5/9th of the work is completed.
Now, let x workers be employed to work 8 hours a day for the rest 18 days to complete 4/9th of the work.
M1D1T1W2 = M2D2T2W1
54*30*10*4/9 = x*18*8*5/9
x = 90
Hence, 36 more workers should be employed.
