Question

The sum of the successor and predecessor of 100 is (a) 101 (b) 199 (c) 200 (d) 111

Answer 1

The sum of successor and predecessor of 100 is 200

Answer 2

The sum of the successor and predecessor of 100 is 200.

* Predecessor refers to the number that just comes before a given number.

So, the predecessor of 100 is 100-1 = 99

* Successor refers to the number that just comes after a given number.

So, the successor of 100 is 100+1= 101

Therefore, on addition of the predecessor and successor we get 99+101= 200.
