SAT Math Question of the Day

Math Category: Percent:

Q: 100 bottles of beer on the wall. Joe drinks 4 of them, tosses them on the ground, and knocks 1/3 of the remaining bottles off the wall. How many bottles are left on the wall?

  1. 32
  2. 42
  3. 64
  4. 68
  5. 96

UNANSWERED.

The correct answer is C.

A: 64. 100 - 4 = 96. (1/3) * 96 = 32. So 32 bottles join the 4 bottles already on the ground, for a total of 36. That leaves 64 (100 - 36) bottles of beer on the wall.
