Direction: Study the following information to answer the given questions:
Ajay would do five tasks: A, B, C, D and E, stating at 9 am in the morning. A is the first task and takes two hours. B can be done after A is completed and requires 1 hour. Work on C which would take 1 hour can start only after A and B are complete. Ajay can do task D along with B and C and would take 3 hours for that. Activity E with duration of 1 hour can start on completion of A, B, C and D.
-
What is the earliest time when Ajay would compete C?
-
- 11 am
- 12 noon
- 1 pm
- 2 pm
Correct Option: C
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
