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. |
If Ajay takes 2 hours for B and completes other preceding tasks without delay, when can E start? |

✖ A. |
12 noon |

✖ B. |
3 pm |

✔ C. |
2 pm |

✖ D. |
1 pm |

**Solution:**

Option(**C**) is correct

Whether there is a delay for B or not, does not change the time when D gets over as to complete D Ajay needs 3 hrs.

∴ Ajay will complete D at 2 pm.

∴ He can start E at 2 pm.

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