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.
A. I alone sufficient while II alone not sufficient to answer B. II alone sufficient while I alone not sufficient to answer
C. Either I or II alone sufficient to answer D. Both I and II are not sufficient to answer
E. Both I and II are necessary to answer

-
- OPT 2 is alone enough as it has mentioned the avg candidate/day and relation with other panels.
let x be the number of candidate interviewed by A.
=> x+x-1+x-2=45
3x=48
x=16
so panel A interviewed 16 candidates/day - 12 years agoHelpfull: Yes(19) No(0)
- op E!!!
from 1)A+B+C=45
from 2)A=C+2 and A=B+1
so both are required:) - 12 years agoHelpfull: Yes(1) No(11)
- a+b+c=15*3=45
a=c+2
a=b+1 so e is the answer - 12 years agoHelpfull: Yes(1) No(3)
- 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). - 6 years agoHelpfull: Yes(0) No(0)
