Question 123
What is the ratio of the total number of students of college N in all years to the total number of students of all the colleges studying in the year 2011 ?
Solution
Total number of students of college N in all years = 330 + 380 + 390 + 360 + 340 = 1800
Total number of students of all the colleges studying in the year 2011Â = 430 + 390 + 440 + 440 + 440 = 2140
=> Required ratio = $$\frac{1800}{2140}=\frac{90}{107}$$
