Answer:
6 days
Step-by-step explanation:
A can do the work in 1 day = 1/10
B can do the work in 1 day = 1/15
A and B both can do together the same piece of work in 1 day,
= (1/10)+(1/15)
= (3+2)/30
= 5/30
= 1/6
To make the work complete we must make it as whole, so we will multiply by 6 (i.e.,) 1/6 * 6 = 1.
Therefore,A and B both can do together the same piece of work in 6 days.
