The Answer E.

The statements alone are not sufficient. When the two statements are combined:
%93 + %94 = 90
%94 +%95 = 90
We can deduct that People aged 93 & 95 must have the same % and it must be <= 10% (so that total % is not over 100).
Some examples that fit in are:

%93 --- % 94 --- % 95
1 --- 89 --- 1
3 --- 87 --- 3
10 --- 80 --- 10
This information is not enough to narrow down to one answer for percentage of people aged 93 & 95.

Unless there are only three age groups. In which case it is option C.
