I can't help you, but I can provide an example related to this question.
In the 2009-2010 school year in country A, there were 116,000 foreign students from country B. In the 2009-2010 school year in country A, there were 116,000 foreign students from country B. This number is 22% more than the number of students from country C. How many foreign students were from country C?
If x represents the number of students from country C.
then 122% of x = 116,000
122/100 * x = 116000
Transposing the formula for x;
therefore x = 116000 * 100/122 = 95,082 students
