How many visitors saw the exhibition yesterday ?

Statements:

1. Each entry pass holder can take up to three persons with him/her.

2. In all, 243 passes were sold yesterday.

  • A.1 alone is sufficient while 2 alone is not sufficient
  • B.2 alone is sufficient while 1 alone is not sufficient
  • C.Either 1 or 2 is sufficient
  • D.Neither 1 or 2 is sufficient

Answer: D

Correct answer: Neither 1 or 2 is sufficient

Statement 2 gives 243 passes and statement 1 says each holder may bring up to three others. “Up to” is the difficulty: the total lies anywhere between 243 and 972, and nothing says how many actually brought companions. Both statements together give a range, not a number.
