Week of the Year 

Manisha prefers her date to be tall, dark and handsome. Of the preferred traits - tall, dark and handsome - no two of Anuj, Balbir, Chiman and Debjit have the same number.
Only Anuj or Debjit is tall and fair.
Only Balbir or Chiman is short and handsome.
Anuj and Chiman are either both tall or both short.
Balbir and Debjit are either both dark or both fair.
Who is Manisha's date?
As no two of them have the same number of preferred traits - from (1), exactly one of them has none of the preferred traits and exactly one of them has all the preferred traits.
From (4) and (5), there are only two possibilities:
* Anuj & Chiman both are tall and Balbir & Debjit both are fair.
* Anuj & Chiman both are short and Balbir & Debjit both are dark.
But from (2), second possibility is impossible. So the first one is the correct possibility i.e. Anuj & Chiman both are tall and Balbir & Debjit both are fair.
Then from (3), Balbir is short and handsome.
Also, from (1) and (2), Anuj is tall and fair. Also, Debjit is the person without any preferred traits. Chiman is Dark. Anuj and Chiman are handsome.
Thus, following are the individual preferred traits:
Chiman - Tall, Dark and Handsome
Anuj - Tall and Handsome
Balbir - Handsome
Debjit - None
Hence, Chiman is Manisha's date.

 A bag of Apricots was divided between Amitabh and Abhitabh. Abhitabh said, "It's not fair! You have 3 times as many Apricots I have." Amitabh said, "OK, I will give you one Apricot for each year of your age." Abhitab replied, "Still not fair. Now, you have twice as many Apricots as I have." "Dear, that's fair enough as I am twice older than you", said Amitabh. Amitabh went to Kitchen to drink juice. While he was in Kitchen, Abhitabh took apricots from Amitabh's pile equal to Amitabh's age. Who has more apricots now?
Let's assume that initially Abhitabh got N apricots and his age is T years. Hence, initially Amitabh got 3N apricots and his age is 2T years.


Amitabh's Apricots

Abhitabh's Apricots




Amitabh gave T apricots to Abhitabh

(equals age of Abhitabh)

3N - T

N + T

Abhitabh took 2T apricots from Amitabh's pile (equals age of Amitabh)

3N - 3T

N + 3T

It is given that after Amitabh gave T apricots to Abhitabh, Amitabh had twice as many apricots as Abhitabh had.
3N - T = 2*(N + T)
3N - T = 2N + 2T
N = 3T
From the table, at the end Amitabh has (3N - 3T) apricots and Abhitabh has (N + 3T) apricots.
Substituting N = 3T, we get
Amitabh's apricots = 3N - 3T = 9T - 3T = 6T
Abhitabh's apricots = N + 3T = 3T + 3T = 6T
Thus, at the end Amitabh and Abhitabh, both have the same number of apricots.
