A certain business school has a student body of 2,000 students, 45% of

2000 total students. 45% i.e. 900 male so 1100 female. We need the total of International students.

Statement 1:

Make the table:

.......................Regular................International...........Total

Male...................................................2x......................900

Female..................x......................................................1100

Total...............................................................................

There is no way to know the total number of international students.

Statement 2:

.......................Regular................International...........Total

Male......................4x.............................2x....................900

Female..........................................................................1100

Total...............................................................................

We get that 6x = 900 so x = 150. But there is no way to know the number of female international students.

Both together:

.......................Regular................International...........Total

Male......................600.............................300....................900

Female...................150...............................y.......................1100

Total...............................................................................

Female international students = 1100 - 150 = 950 = y
Total number of international students = 300+950
We can find the desired % now.
