Question

A can complete a work in 6 days and B can complete it in 8 days .If they work on it together how long will it take to complete the same work.i) find A's and B's one day work ii) Time taken by A and B to complete the work together​

Answer 1

Answer:

We will solve this using the LCM technique.

A takes 6 days & B takes 8 days. So, let the total work be LCM(6,8) = 24 Units

A -> 6 days = 4 Units/day

B -> 8 days = 3 Units/day

A + B = 7 Units/day

Thus, TOTAL TIME = 24/7 =

$3 \frac{3}{7}$
