Question


Choose the correct statements.
(There can be more than one correct answer!)


Options:
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: Option B
:
B and D

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.
