The percentage of sugar in a solution of sugar and water is 9%. 4 litres of this is diluted by adding 500ml of water, what is the percentage of sugar in the new solution?

Respuesta :

S:W = 9:91  

here 4 lt equivalent to 100 

initally, Sugar:Water = 36/100: 364/100

finally, S:W = 36/100 :364/100 +50/100

> 36/100 : 414/100

sugar %  =( 36/ 450 )* 100 = 8 %
