The two fruits are in 3+5=8 parts. But this fact will not be needed for the question(s).

A.

cross%28r%2F240=5%2F8%29
r%2F240=5%2F3

r=%285%2A240%29%2F3

r=5%2A80
r=400

            The solution by @josgarithmetic is INCORRECT.

            The correct solution is below. 


(A)  Use the proportion

         strawberries%2Fraspberries = 3%2F5 = 240%2Fr.


     From the proportion,  r = %28240%2A5%29%2F3 = 80*5 = 400 grams.   ANSWER



(B)  Use the same proportion

         strawberries%2Fraspberries = 3%2F5 = s%2F800.


     From the proportion,  s = %28800%2A3%29%2F5 = 160*3 = 480 grams.   ANSWER

Solved.
