The barrel is 199 litres of 38% acid. How many percent acid occurs when 61 litres revoke and replace it with the same amount of water?

Correct result:

acid concentration =  26.4 %


c=1996119938=26.4%c = \dfrac{ 199-61}{ 199} \cdot 38 = 26.4 \%

We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
