589654237, 89654237, 8965423, 965423, ?

  • A.58965
  • B.65423
  • C.89654
  • D.96542

Answer: D

Correct answer: 96542

A digit is struck off each time, alternately from the front and from the back: 589654237 loses its first digit, the result loses its last, and so on. Taking the last digit off 965423 gives 96542.
