here are my two cents for this question



Avg interest is \( \frac{4080}{60,000} \) =6.8 ( hidden information in Stem)

Using concept of allegations

We have a information that is represented by figure 1 ( From Question Stem)
we can see that we need values of X or Y and 'a' or 'b'. IN this regard if we have any relation in term of X and Y and some relation between 'a' and 'b' .

Now from statement 1:
we have a relation between X and Y but we don't have any relation or values of 'a' and 'b'.

Now from statement 2:

"The ratio of the amount that earned interest at the rate of x percent per year to the amount that earned interest at the rate of y percent per year was 3 to 2." This information gives a relation between 'a' and 'b'
But in absence of any information regarding "X" and "Y" we cannot find out the value of "X"

Combining both statements we do have information of "x" and "y" and also information about 'a' and 'b'


Hence Answer C

Avg interest is \( \frac{4080}{60,000} \) =6.8 ( hidden information in Stem)
