    Given takes are A, B, C, D, E (here we will assume the condition to complete the work at the earliest)
    From the 1stcondition- Task A → from 11 am to 9 am to 11 am,
    From the 2nd condition B → From 11 am to 12 noon (Since it has started after completion of A)
    From the 3rd condition C → From 12 noon to 1 pm
    Task D's one hour work will be done along with B.
    D's second hour work will be done along with C.
    Hence to commence E, D must complete 3 hrs.
    Hence timing of task D → from 11 am to 2 pm and
    After this the remaining task E → From 2 pm to 3 pm
