Answer:

-52.5 or -105/2

Step-by-step explanation:

Let the certain number be x

ATQ (According to Question),  (x + 90) 4 = 150

                                                              4x = 150 - 360

                                                                x = -210/4

                                                                x =  -52.5 or -105/2
