Select the option that is related to the third number in the same way as the second number is related to the first number in the pair.
435 : 216 :: 1087 : ?

  • A.868
  • B.867
  • C.872
  • D.888

Answer: A

The missing number is 868. In the pair 435 : 216, the second number is 219 less than the first (435 - 219 = 216). Applying the same relation to the third number, 1087 - 219 = 868. The other options (867, 872, 888) would need the difference to be 220, 215 or 199, which does not hold for the given pair.
