Determine the sum of the four numbers as given below:

(a) successor of 32


(b) predecessor of 49


(c) predecessor of the predecessor of 56


(d) successor of the successor of 67

Successor of 32 = 32 + 1 = 33


Predecessor of 49 = 49 - 1 = 48


Predecessor of predecessor of 56 = predecessor of 56 - 1 = 56 - 1 - 1 = 54


Successor of successor of 67 = successor of 67 + 1 = 67 + 1 + 1 = 69


Hence, their sum,


= 33 + 48 + 54 + 69


= 204
