If the numbers X + 2, X + 5, 2X − 3 and 3X − 5 are in proportion, then which of the following pairs of values is possible for X?

  1. A.5 and 1✓ Correct
  2. B.3 and 2
  3. C.4 and 2
  4. D.5 and 3

Explanation

For proportion: (X+2)(3X−5) = (X+5)(2X−3). Expanding and simplifying gives x²−6x+5=0, so (x−1)(x−5)=0, yielding x=1 or x=5.
