Answer: 56.9
Step-by-step explanation:
Let the original number be denoted by x.
We are informed that when the number is increased by 5.5%, the result is 60. This can be represented by:
x + (5.5% of x) = 60
x + (0.055 × x) = 60
x + 0.055x = 60
1.055x = 60
x = 60/1.055
x = 56.9
The original number is 56.9
