Q156 / 270 · NDA 2013 (Phase 2) · Mathematics

If the three vertices of the parallelogram $A B C D$ are $\mathrm{A}(1, a), \mathrm{B}(3, a), \mathrm{C}(2, b)$, then D is equal to

  • A
    (3,b)
  • B
    (6,b)
  • Correct answer
    C
    (4,b)
  • D
    (5,b)

Solution

Note: In the given question, it should be ' $\mathrm{D}(2, b)$, then c is equal to' in place of ' $\mathrm{C}(2, b)$, then D is equal to' and so we will get correct option $\mathrm{C}(4, b)$.

Hence, the correct answer is option: 'C'.
