    Two typists of varying skills can do a typing job in 6 minutes if they work together. If the first typist typed alone for 4 minutes and then the second typist typed alone for 6 minutes, they would be left with 1/5 of the whole work. How many minutes would it take the slower typist to complete the typing job working alone?

    Solutions

    Working efficiency of both typist together =  100/6
    = 16.66%
    Let the efficiency of first typist be x and second
    typist be (16.66 – x)
    First typist for 4 minute + second typist for 6 minute
    = 80% work
    ⇒4x + (16.66 – x) X 6 = 80%
    ⇒4x + 100% - 6x = 80%, ⇒x = 10%
    First typist typed 10% per minute, second typist
    typed (16.66 – 10) = 6.66% per minute
    Slowest is second typist complete whole job in
    100/6.66 = 15.01 = 15 minute
