One could only assume you mean mass per mass.

Only doing ONE example, and you figure the others.

30% sugar syrup from 7 grams of sugar:
Adding x GRAMS of water,
75%2F%2875%2Bx%29=0.30
-
75=0.3%28x%2B75%29
75=0.3x%2B22.5
0.x=%2875-22.5%29%2F0.3
x=175

Total mass of these two materials will be 75%2B175=250 grams.

What weight of sugar syrup would you get if you made: 

1) 10% sugar syrup from 80g of sugar     0.1x = 80  ====>  x = 80%2F0.1 = 800 grams.

2) 70% sugar syrup from 350g of sugar    0.7x = 350  ====>  x = 350%2F0.7 = 500 grams.

3) 5% sugar syrup from 6g of sugar

4) 30% sugar syrup from 75g of sugar


Do the rest in the same way.
