<1> The ratio of Jean's insurance premium in 1995 to her insurance premium in 1994 was 6/5.
<2> Jean's insurance premium in 1995 was 20% more than her insurance premium in 1994.
Key: <1>&<2> both are not sufficient.
If in 1994 is x, then 1995 could be x(1+20%). So x could be solved by <1> and <2> together. Isn't it?
