As per given graph ,
Number of products not sold by the company in the year 2007 = Number of products manufactured − Number of products sold = 45  42.5 = 2.5 ( in thousands )
Number of products not sold by the company in the year 2005 = Number of products manufactured − Number of products sold = 37.5  30 = 7.5 ( in thousands )
∵ ratio = Number of products not sold by the company in the year 2007 : Number of products not sold by the company in the year 2005
= 2.5 : 7.5 = 1 : 3
