Let 90% pure acid solution be A litre and 97% pure acid solution B.
A+B=21
90% of A+ 97% of B=95% of 21
= 90A/ 100+97B/ 100=95* 21/100
90A+97B= 1995
By solving A= 6. B= 15
So 97% of pure acid is 15 litres.
A+B=21
90% of A+ 97% of B=95% of 21
= 90A/ 100+97B/ 100=95* 21/100
90A+97B= 1995
By solving A= 6. B= 15
So 97% of pure acid is 15 litres.
