Step-by-step explanation:

Given two farmers, Ramesh and suresh, can harvest a field in 5 days and 7 days respectively. After Ramesh has worked for 3 days he is joined by suresh. in how many more days will they complete the harvesting

  • Ramesh’s one day work will be 1/5
  • Suresh ‘s one day work will be 1/7
  • Ramesh worked alone for 3 days and so work completed will be 3 x 1/5 = 3/5
  • So work left will be 1 – 3/5 = 2/5
  • Now Suresh joins Ramesh
  • Work done by both in one day will be Ramesh + Suresh ‘s one day work.
  •                                                          1/5 + 1/7
  •                                                           = 12/35
  • Now 12/35 of work is completed in one day
  • Therefore 2/5 of work will be completed in 35/12 x 2/5 = 70 / 60
  •                                                                                            = 7/6 days

Given : Ramesh and suresh, can harvest a field in 5 days and 7 days respectively

After Ramesh has worked for 3 days he is joined by suresh

To Find  : in how many more days will they complete the harvesting

Solution:

Ramesh, can harvest a field in 5 days  

=> Ramesh can harvest in 1 day = 1/5

Suresh, can harvest a field in 7 days

=> Suresh, can harvest  in 1 day  = 1/7

Both can harvest in 1 day  = 1/5 + 1/7   = 12/35

Ramesh has worked for 3 days = 3(1/5)  = 3/5

Remaining Work = 1 - 3/5  = 2/5

Number of days further required  = (2/5)/(12/35)

= 70/60

= 7/6 Days

7/6  more Days

and 3 + 7/6  = 25/6 Days altogether
