A sells his goods 50% cheaper than B but 50% dearer than C. The cheapest is_________?

Correct answer: C. C

  • A. A
  • B. B
  • C. C
  • D. All Alike

Explanation

If A is 50% cheaper than B, then A = 0.5B. Since A is 50% dearer than C, A = 1.5C, so C = A/1.5, which is less than A; therefore C is the cheapest. The likely mistake is focusing only on A being cheaper than B and choosing A.
