Answer:
Step-by-step explanation:
A can do its total work in = (3 X 5)days
= 15 days
A can do its total work in = (2 X 6)days
= 12 days
In 1 day part of work A can do = 1/15
In 1 day part of work B can do = 1/12
In 1 day part work done by A and B together can do = 1/15 + 1/12
= [(4 + 5)/60]
= 9/60
Therefore A and B together will complete the work in 60/9 days.
= 6.67 days
= (6 + 2/3) days
