You can put this solution on YOUR website!
Make it to 40% from the start.
x, how much sugar to add.

x%2F%28x%2B60%29=0.4
x=0.4%28x%2B60%29
x=0.4x%2B24
0.6x=24
x=24%2F%280.6%29
highlight%28x=40%29

Observe and follow the method if you still wanted what would be the concentration
for the first part question. That would be 20%2F80 which is 25%.
