  Jasminder estimates that 3 persons could rewire her house in 4 days. If she uses 4 persons instead of three, how long should they take to complete the job?

  This particular question can be solved using the unitary method (this method include solving the problem for 1 unit and then multiplying it with how many units are required), which is proceded as :-

  3 persons can rewire the house in = 4 days

  1 person can rewire the house in = 3/4 days

  Hence, 4 persons can rewire the house in = (3/4)×4 days

  =3 days.

  (Now writing the proper statement at the end to complete the answer)

  So, if Jasminder uses 4 persons using 3 to rewire her house, it will take 3 days.
