Answer:
Old number = 150
Step-by-step explanation:
Given information;
Percentage decreased = 22%
New number obtain = 117
Find:
Old number
Computation:
Old number = New number obtain[100 / (100 – 22)]
Old number = 117[100 / (100 – 22)]
Old number = 117[100 / (78)]
Old number = 11,700 / 78
Old number = 150
100-22=78
117=78%
117/78=1.5
1.5=1%
1.5 x 100=150
