Question

somesh, Ramesh,and Rajesh can complete a work separately in 45,60 and 75 days . they started the work together but Rajesh left after 5 days and somesh left 2 days before the completion of work . in how many days will the work be complete ?​

Answer 1

Answer:

27 days

Step-by-step explanation:

5*(1/45+1/60+1/75)=235/900 =47/180 work done in 5 days

133/180 amount of work left

somesh and ramesh in one day can do (1/45+1/60) = 7/180th of the work, so the remaining can be finished in 19 days but somesh leaves two days prior to that. This implies 119/180th of the work is done. so total number of days worked is 17+5. work left os 14/180 will be finished by rajesh in 14/180/3/180 = 5 approx days

Therefore 17+5+5=27days
