- Give answer (A) if the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
- Give answer (B) if the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
- Give answer (C) if the data either in Statement I or in Statement II alone are sufficient to answer the question.

How many candidates were interviewed everyday by the panel A out of the three panels A, B and C? | |
I. | The three panels on average interview 15 candidates every day. |
II. | Out of a total of 45 candidates interviewed everyday by the three panels, the number of candidates interviewed by panel A is more by 2 than the candidates interviewed by panel c and is more by 1 than the candidates interviewed by panel B. |
I. Total candidates interviewed by 3 panels = (15 x 3) = 45.
II. Let x candidates be interviewed by C.
Number of candidates interviewed by A = (x + 2).
Number of candidates interviewed by B = (x + 1).
x + (x + 2) + (x + 1) = 45
3x = 42
x = 14
Hence, the correct answer is (B).
Then C equals to (x-2) & B equals to (x-1).
So statement B is correct but answer is 16 instead of 14.
In II statement they clearly mentioned 45 student so no need of first statement.
Means A=c+2 and A=B+1.
This implies,
B+1=c+2 thus B=c+1.
Didn't understood.
Please help.
Eg we take C = 1.
Then A is more then C so A = C+2 or 2+C.
B = C+1.
