Let x = pounds at 10/lb and Y = 30 pounds at 4/lb and Z = 30 +x = total pounds at 6/lb;
then 10X + 4Y = 6Z
solve for x
10x + 120 = 180 + 6x
x = 15 pounds
Apart from the fact that bananas do not own strawberries, there is not enough information to answer the question.
6 (worth 12 units,) added to the 4 units gives 10 units worth 24. (This is the sort of problem we used to get at Primary school in the 1950's. It's probably University Entrance standard nowadays!)
You need 17 gallons for a 15% volume/volume mixture.
266 should be added.
There are 3 litres of alcohol in your starting mixture of 4 litres. If you add 6 litres of water you will have 3 litres of alcohol in a total of 10 litres. This is the required strength.
Cafe mocha is coffee with chocolate added
If you have added milk and/or sugar to your hot coffee, you will have to stir it well, in order to obtain a homogeneous mixture.

It really depends on what the hot mixture is. It is generally ok.
500 gallons of pure water weigh 4,172.6 pounds (rounded) With 250 pounds of salt added, the mixture had better weigh 4,172.6 + 250 = 4,422.6 pounds, or else mass has disappeared, which is a no-no.
Coffee doesn't have sugar unless it is added to the coffee.
