A can finish a work in 8 days and B can do same work in half the time taken by A. then working together, what part of same work they can finish in a day?
Select the correct option
A) 3/5 B) 3/6 C) 3/7 D) 3/8 E) None of these
Explanation:   Please note in this question, we need to answer part of work for a day rather than complete work. It was worth mentioning here because many do mistake at this point in hurry to solve the question   So lets solve now,   A's 1 day work = 1/8   B's 1 day work = 1/4 [because B take half the time than A]   (A+B)'s one day work =   (1/8+1/4)=3/8   So in one day 3/8 work will be done   Answer: 3/8
<result>D</result>
A can finish a work in 8 days and B can do same work in half the time taken by A. then working together, what part of same work they can finish in a day?
