If you mean: % by MASS ( %m/m), it's quite easy to do (based on the 'Mass Conservation Law).
However if the meaning was: % by Volume ( %v/v) then calculation appears to get very complicated, but not impossible if you know at least the density values of all solutions (original 95%v/v and final 10%v/v) and of the solvent.
(In that case mail me: JoppeDeQuint at answers dot com).
DO NOT ever use: (orig. volume) + (added volume) = final volume.
It's only a rule of thump, an approximation. This is because fluids can contract on mixing at dilution. There is no rule such as: conservation of volume.
Your case: 10 ml + 85 ml (is not equal but) < 95 ml final solution.
10% of 95 = 99.75
Solution if one acts before thinking:91% of 250 = 227.595% of 250 = 237.5(237.5) - (227.5) = 10 extra marks required to raise score to 95%.===============================================Solution if one thinks before acting:Additional score required = (95% - 91%) = (4% of 250) = 10 marks
$950.00 - 10% = $95
950 percent as a fraction = 95/10 or 19/2 950% = 950%/100% = 95/10 or 19/2 in fraction
nineteen twentieths as a percent = 95% 19/20 * 100% = 9.5 * 10% = 95%
Solution for What is 5.4 percent of 95: 5.4 percent *95
253000 is 100 percent. 253000/100 = 2530 is 1 percent. This value times 95 gives you the 95 percent. Solution: 240350
To find 95 percent of a number, multiply that number by 0.95. In this instance, 0.95 x 10 = 9.5. Therefore, 95 percent of 10 is equal to 9.5.
To find the percentage of 9.5 out of 10, you would divide 9.5 by 10 and then multiply by 100. This calculation gives you 95%. Therefore, 9.5 is 95% of 10.
10% of 95 = 99.75
10% of $95 is $9.50

Solution if one acts before thinking:91% of 250 = 227.595% of 250 = 237.5(237.5) - (227.5) = 10 extra marks required to raise score to 95%.===============================================Solution if one thinks before acting:Additional score required = (95% - 91%) = (4% of 250) = 10 marks
