When 106 is subtracted from a number, it reduces to its 47%. What is 11.5% of that number?

Correct option is C

Solution:

Let the unknown number be x . According to the problem, when 106 is subtracted from x , it becomes 47% of itself.
Thus, we have the equation:
x - 106 = 0.47x

Rearrange the equation to solve for x :

Now, calculate 11.5% of x :
​$$11.5\% \text{ of } x = 0.115 \times 200$$​​
= 23

11.5% of the number is 23 .
