25% amount = x        medicine amount =   .25x

3% amount = (10-x)  medicine amount  = .03(10-x)

 

Final amount = 10   medicine amount =  .08 ( 10)           ingredients summed = final amount

 

.25x        +      .03(10-x)            =       .08 (10)    

                                                                     solve for x, the 25% amount ...  then 3% amount = 10 -x
