Direction: Read the following information carefully and answer the fo...
From the Statement 1
Total student in college A and B = 220
Statement 2:
Ratio of student in college A and B = 6 : 5
So, Number of student in college A = (220/11)×6=120
Number of student in college B = 220 - 120 = 100
Number of student in college B from Mumbai = 30% of 100 = 30
Statement 3:
Number of student of Mumbai in college B = 75% of Number of student of Patna in college A
Number of student of Patna in college A = (30/75)×100=40
Statement 4:
Number of students from Delhi in college B = 62.5% of the number of students from Patna in college A
Number of student from Delhi in college B =(⅝)×40=25
Number of student from Patna in college B = 100 - 30 - 25 = 45
Ratio of students from Patna in college B and number of students from Mumbai who studies in college A = 9 : 10.
Number of student from Delhi in college B =(⅝)×40=25
Number of student from Delhi in college A = 120 - 40 - 50 = 30
Ratio of student from Delhi in college A and college B = 30 : 25
= 6 : 5
∴ The required answer is 6 : 5.
Hence, the correct option is (C).
