Question: The last Sunday of March, 2006 fell on which date ?

Statements:

  1. The first Sunday of that month fell on 5th.
  2. The last day of that month was Friday.

[A]. I alone is sufficient while II alone is not sufficient
[B]. II alone is sufficient while I alone is not sufficient
[C]. Either I or II is sufficient
[D]. Neither I nor II is sufficient
[E]. Both I and II are sufficient

Answer: Option C

Explanation:

From I, we conclude that 5th, 12th, 19th and 26th of March, 2006 were Sundays.

So, the last Sunday fell on 26th.

From II, we conclude that 31st March, 2006 was Friday. Thus, 26th March, 2006 was the last Sunday of the month.

When the condition comes (both 1 and 2 are sufficient) and (either 1 or 2 is sufficient) , i.e., difference between these conditions.

Deepa said: (Feb 6, 2015)  
In option E both the statements should be provided. So that it is sufficient, in option C anyone statement is enough.

Statement 1 alone will suffice actually. Because 5 + 3 * 7 = 26th march.

What if the year is a leap year we can know the date coming from the last day of the year. Is the answer right?

Bhavesh Doda said: (Dec 26, 2016)  
How, C option is correct? Explain.

Subhadeep said: (Jul 1, 2017)  
Here 2006 is a leap year or not is not given, so we can't asume it.

Prakyath said: (Oct 24, 2017)  
While solving problem using statement 2. They have assumed that March month has 31 days ! It may have 30 days as well ! So we can't predict directly that March has 31 days!

So, according to me the answer should be D.

Gopal Halder said: (May 26, 2021)  
The right answer is option E because if 31th march of 2006 is Friday then 26th march of 2006 is Sunday.
