Question

In a mixture of 45 litres, the ratio of sugar solution to salt solution is 1:2. What is the amount of sugar solution to be added if the ratio has to be 2:1?​

Answer 1

SOLUTION :

           Number of litres of sugar solution in the mixture = (1/(1+2)) *45 = 15 litres.

So, 45-15 = 30 litres of salt solution is present in it.

Let the quantity of sugar solution to be added be x litres.

Setting up the proportion,

sugar solution / salt solution = (15+x)/30 = 2/1 → x = 45.

Therefore, 45 litres of sugar solution has to be added to bring it to the ratio 2:1.

Answer 2

Answer:

45l.

Step-by-step explanation:

because, quantity of mixture =45l.

ratio =1:2.

amount of sugar solution =1+2=3,

45÷3

=15l.

asusual amount of salt solution =30l.

so we add some more amount of sugar solution to it = 45+15 =60L.

60:30=60/30=1:2
