Question

A can complete a work in 24 days. If B works twice as fast as A, in how many days they together will complete the work?
(a) 5 days
(b) 6 days
(c) 8 days
(d) 9 days ​

Answer 1

Answer:

8 days

as a takes 24 days, b works twice as fast therefore it will take 12 days since both are combining therefore now 1/24 +1/12 =1/8 therefore 8 days
