Answer 2

Answer:

29) So percentage of foreign students in science is 11%.

30) Number of Engineering faculty is 410

31) Percentage of European medical students is 15%

Step-by-step explanation:

Given total number of science students = 1049

29) Percentage of science students = 23%

• Total number of students = X
• X = No. of science students / percentage of science students.
• X = (1049 × 100) /23
• X = 4561
• so total number of students is 4561
• Total number of foreign science students

= No. of american students + number of African students+ number of chinese student + number of European students + Number of Australian students.

= 79 + 2 + 6 + 21 + 4 = 112

• Percentage of foreign students in science faculty = (No. of foreign students / No. of science students) × 100

= (112/ 1049 ) × 100 = 11%

• So percentage of foreign students in science is 11%.

30) Given total Number of students = 4561

Percentage of Engineering faculty = 9%

• Number of Engineering faculty =

9% of 4561

=( 9 × 4561) / 100

= 410

• Number of Engineering faculty is 410.

31) Given total Number of students = 4561

Percentage of medical students = 5%

Number of medical students =

5% of 4561

= ( 5× 4561)/ 100

= 228

Total number of medical students = 228

Number of European medical students = 34

percentage of European students =

= (34/228) × 100

= 15%

Percentage of European medical students is 15%
