correct question: A can do a work in 21 days and B can do the same work in 23 days . if they worked together then in how many days will the work be finished.
solution:
-------------
let total work done = 1
A's 1 day's work = 1 / 21 units
B's 1 day's work = 1/ 23 units
On working together:
------------------------------
(A + B)'s 1 day's work = (1/ 21) + ( 1/ 23)
= (23 + 21)/ 21 × 23 = 44/ 483
= 1/ 10.9 units
Answer:
the work will be finished in 10.9 days.
