(2) Number of medium sized packets bought by Radhika was 15 more than that of the large sized packets, and was 10 more than that of the small sized packets.

Statement 1- We only get the ratio of number of small packets to large packets. This statement is insufficient.

Statement 2-
Let the number of Small packets, Medium packets and Large packets be x,y and z respectively
According to the statement- y=z+15 and y=x+10
=> z+15=x+10, x-z=5
Thus Statement 2 is also not sufficient

Combining Statement 1 and 2,
x:z=3:2
=>x=3/2z
Using the above in equation in Statement 2-
3/2x-x=5
Therefore x=10
