Question

A can finish a work in 18 days and B can do the same work in half the time taken by A. Then working together, which part of the same work they can finish in a day?

Answer 1

Answer:

1/6

Step-by-step 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 = 1/18

B's 1 day work = 1/9 [because B take half time than A]

(A+B)'s one day work =

\begin{aligned}

\left(\frac{1}{18}+\frac{1}{9} \right) \\

=\left(\frac{1+2}{18} \right) \\

= \frac{1}{6}

\end{aligned}

So in one day 1/6 work will be done.
