Answer:

4 days

Step-by-step explanation:

Given,

A can finish a work in 6 days

A=1/6 days

B can finish the same work in 12 days.

B=1/12 days

Find the number of days required  by A and B to finish the work, if they work together.​

A+B=1/6+1/12

A+B=3/12

A+B=1/4

Answer 2

Step-by-step explanation:

A can finish a work =6 days

work done by A in 1 days = 1/6

B can finish a same work = 12 days

work done by B in 1 days = 1/12

work done by A and B both = 1/6 + 1/12 = 3/12

= 1/4

= 4 ans
