The product of the predecessor of 201 and the successor of 4781 is :

  • A.965560
  • B.965650
  • C.956200
  • D.956400

Answer: D

The product is 956400.

The predecessor of a number is the number just before it, and the successor the number just after it. So the predecessor of 201 is 200 and the successor of 4781 is 4782.

\[ 200 \times 4782 = 956400 \]

Option C, 956200, is 200 × 4781, from forgetting to take the successor. 965560 and 965650 come from mixing up the digits. A quick check is that any multiple of 200 must end in 00, which rules both of those out at once.
