Algebra.Com's Answer #403163 by sachi(548)![]() ![]() You can put this solution on YOUR website! let x ml of 10% & 100-x ml of 15% acid soln were mixed to get 100 ml of 12% soln \n" ); document.write( "so 10x/100+15[100-x]/100=12 \n" ); document.write( "or 10x+15[100-x]=1200 \n" ); document.write( "or -5x=1200-1500=-300 \n" ); document.write( "or x=60 ml of 10% & 40 ml of 15% soln were mixed \n" ); document.write( "ans \n" ); document.write( " \n" ); document.write( " |
