Quantitative comparisonQuestion 521 of 550

Compare the two quantities: a and b are whole numbers that are not negative. Quantity A: √a + √b Quantity B: √(a + b)

  1. Quantity A is greater
  2. Quantity B is greater
  3. The two quantities are equal
  4. The information is not enough
Show answer

Correct answer: The information is not enough

If a = 0 or b = 0, the two are equal. If a = 1 and b = 1, A is 2 and B is √2, so A is greater. We cannot decide.
