Question: How many children are there in the row of children facing North ?

Statements:

  1. Vishakha who is fifth from the left end is eighth to the left of Ashish who is twelfth from the right end.
  2. Rohit is fifth to the left of Nisha who is seventh from the right end and eighteenth from the left end.

[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:

Since 8th to the left of 12th from the right is 20th from the right, so from I, we know that Vishakha is 5th from left and 20th from right i.e. there are 4 children to the left and 19 to the right of Vishakha. So, there are (4 + 1 + 19) i.e. 24 children in the row.

From II, Nisha is 7th from right and 18th from left end of the row.

So, there are (6 + 1 + 17) = 24 children in the row.

They asked how many children facing north. But in the 2 options they didn't mention about the direction.

Navrata said: (Jan 7, 2012)  
Same here. No direction. How is possible ?

Harshita said: (Jan 20, 2012)  
Same Question of Jeeva and Navrata.

Trom statement 1: 5 4 3 2 1(from left end).
(vishaka 5th).
8 7 6 5 4 3 2 1(from ashish).
(vishaka is 8th now) (from question ashish pstion is 12 th from right end).

Therefore 12+12=24 na,

From statement 2:

6+1+17=24.

Therefore either 1/2 statements will be right yar you got it.

To create confusion they have given as north. Don't go for direction just calculate the the total no.of students sitting in a row.

That's all.

Facing north is the basic sitting position of students.

Given according the question. Ignore the direction blah blah blah.

There is no indication of direction in the options?

Chaitanya said: (Jul 29, 2016)  
Universal directions are not mentioned here.

Jasan said: (May 30, 2017)  
How can we take answer C? Because in 2 statements there isn't mentioned about direction. So the answer should be D.

Sindhu said: (Jun 9, 2017)  
I thought the answer is neither of I and II since direction is not mentioned. This explanation fits for how many children in all (explanation holds excluding the direction part).

Amol said: (Nov 14, 2017)  
I too have same doubt about direction.

Mitesh said: (Feb 27, 2020)  
As it is mentioned north side, for all the students it's measured north side. So answer is C correct.
