If 40 is 100 %Hello,
4% is not correct.
If 40 is 100 %, how many percent is 10.

This is basic math. Out of the 125 gallons of the mixture, 20% is water, so there are 125 * 0.2 = 25 gallons of water.125 gallons of a mixture contains 20% water. What amount of additional water should be added such that water content be raised to 25%?
Oops, I was forgetting something important. When water is added, the total amount of mixture changes, so the problem is more complicated than I was thinking:ok, it was so simple.
I was messing with meaning.
Sorry, but you won't get it unless you solve it the way I showed in post #12.125 gallons of a mixture contains 20% water. What amount of additional water should be added such that water content be raised to 25%?
125 mixture=water + other
125 mixture=25+ 100
for 25%
The water is 31.25
both are same
25+100=31.25+93.75
not getting it.
not getting thats why.Sorry, but you won't get it unless you solve it the way I showed in post #12.
