Question

a and b can polish the building in 25 days .a alone can do 1/3 of the job in 15 days.In how many days can B alone polish the floors of the building.

Answer 1

Answer:

I GUESS IT IS 56.17 days(approximately).

Step-by-step explanation:

Work rate of A and B = 100/25 = 4% per day.

A alone can do 1/3 (33.33%) of work in 15 days. Thus,

Work rate of A = 33.33/15 = 2.22% per day.

Work rate of B = 4 - 2.22 = 1. 78% per day.

Therefore, alone B can polish the floor = 100/1.78 = 56.17 days (Approx.)

ALL THE BEST DEAR.
