(There can be more than one correct answer!)

• A. The predecessor of 7899 is 7900
• B. The successor of 9879 is 9880
• C. The successor of 1230 is 1229
• D. The predecessor of 2589 is 2588

Answer 1

Answer: (B), (D)

The correct options are
B

The successor of 9879 is 9880

D

The predecessor of 2589 is 2588

The predecessor of a number is one less than the number.
The successor of a number is one more than the number.

The successor of 9879 is 9879 + 1 = 9880.
The predecessor of 2589 is 2589 - 1 = 2588.
The predecessor of 7899 is 7899 - 1 = 7998.
The successor of 1230 is 1230 + 1 = 1231.

Hence options B and D are correct.
