Answer 1

Correct Answer - Option 3 : 100%
Given:

	Science	Sociology	Economics	Total in College
A	250	200	400	850
B	300	200	350	850
C	200	400	150	750
D	150	500	350	1000
Total in Seminar	900	1300	1250	3450

Calculation:

Number of students in college B who attended sociology seminar = 200

Number of students in college C who attended sociology seminar = 400

Increase in number of students who attended sociology seminar in C from B = 400 - 200 = 200

Percentage increase = 200/200 × 100 = 100%

∴ The percentage increase is 100%.
