40 g of salt solutions are in both of two beakers A and B each.
The ratio of the concentration of salt solution of A and B is 3 : 2.
I add 60 g of water to B and mixed it well and transferred some of salt solutions in B to A.
Furthermore, I add some water in both of A and B to become 100 g of salt solutions.
The ratio of the concentration of salt solution of A and B was to be 7 : 3.
Find the weight of the salt solution I transferred from B to A.
