Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different.

  • A55-275
  • B45-235
  • C35-175
  • D25-125
Correct answer: B

Explanation

55 × 5 = 275, 35 × 5 = 175 and 25 × 5 = 125, but 45 × 5 = 225, not 235. So 45-235 is different.
