Saleem can type a 20 page document in 40 minutes. Aysha can type it in 30 minutes. and Raheel can type it in 24 minutes. Working together. how much time will it take them to type the same document?

Saleem types (20/40) = 1/2 page per minute.Aysha types (20/30) = 2/3 page per minute.Raheel types (20/24) = 5/6 page per minute.Working together ... IF they can split up the paper appropriately and avoid any duplication ... they can type(1/2) + (2/3) + (5/6)= (3/6) + (4/6) + (5/6)= (12/6) = 2 pages per minute.At 2 pages per minute, they will require (20/2) = 10 minutes to type the same document.

Bill can wash a car in 6 minutes Joe can wash the same car in 8 minutes How much time would it take for them to wash that same car working together?

In 1 minute bill washes 1/6 of a car and Joe washes 1/8 of a car. 1/6 + 1/8 = 14/48. A whole care = 48/48. Therefore you should divide 48 by 14 to get 3.429. However since this is in minutes you need to find how much seconds 0.429 of 1 minute is. 0.429 x 60 = 26 seconds (rounded). Add that to the original three minutes and you have 3 minutes 26 sec to wash the entire car working together.
