What is the ratio of the total number of students of College A in years 2004, 2006 and 2007 together and the total number of students of College B in years 2003, 2004 and 2008?

Given :- Number of students in college A in the years 2004, 2006 and 2007 = 160 × 10³
Also, number of students in college B in the years 2003, 2004 and 2008 = 175 × 10³
Required ratio = Number of students in college A in the years 2004, 2006 and 2007 : number of students in college B in the years 2003, 2004 and 2008
= 160 : 175 = 32 : 35
