How many children are there in the row of children facing North ?
I. Vasudha who is fifth from the left end is eighth to the left of Anish who is twelfth from the right end.
II. Rahul is fifth to the left of Neeta who is seventh from the right end and eighteenth from the left end.
I : Vasudha is 5th from left end.
Anish is 8th to the right of Vasudha => Anish is (8 + 5) = 13th from left end
Also, Anish is 12th from right end
=> Number of students = 13 + 12 - 1 = 24
Thus, statement I alone is sufficient.
II : Neeta is 7th from right end and 18th from left end.
=> Number of students = 18 + 7 - 1 = 24
Thus, II alone is sufficient.
$$\therefore$$ Either statement alone is sufficient.
