Logical Reasoning Discussion

**Common Information**

Ajay would do five tasks: A, B, C, D and E; starting at 9 am in the morning. A is the first task and takes two hours. B can be done after A is complete 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.

Q. |
What is the earliest time when Ajay would complete C? |

✖ A. |
11 am |

✖ B. |
12 noon |

✔ C. |
1 pm |

✖ D. |
2 pm |

**Solution:**

Option(**C**) is correct

Ajay starts to work at 9 am.

Before completing C he has to complete A and B which take 2 hrs and 1 hr respectively and B can be done only after A is over.

∴ A gets over at 11 am.

∴ B gets over at 12 noon.

Now, C takes another 1 hr to complete.

∴ C will get over at 1 pm.

Hence, **option C** is the correct choice.
