Answer 1

Calculation:

Average of students enrolled from college D is

(710 + 750 + 680 + 720 + 740) / 5

= 3600 / 5

Average of students who passed from college D over all the years is

(650 + 710 + 640 + 690 + 710) / 5

= 3400/5

The ratio will be, 3600 / 5 : 3400/5 = 18 : 17

∴ The correct answer is 2
