Question

A completes work in 8 days ,B completes the same work in 4 days , if they started working together then in how many days they will complete work ?​

Answer 1

Answer:

8/3 days

Step-by-step explanation:

Total work can be represented as 1.

Let, n be the no. of days.

FOR A

days taken = 8

work done by A in one day = 1/8

FOR B

days taken = 4

work done by A in one day = 1/4

∴n x (work done by A in one day + work done by B in one day) = 1

n (1/8 + 1/4) = 1

n (3/8) = 1

n = 8/3

therefore, 2.667 or 8/3 days.
