| 20 men can do a work ir dayThey worked 3 days. Then 3 mejoined. How many days requireto complete this work ?

Answer»

Let number of days required to complete work when 3 more men joined = x

Then,20*18 = 20*3 + 23*x

20*(18 - 3) = 23*x

20*15 = 23*x

x = 300/23 = 13

Therefore, 13 more days require to finish work
