There are two solutions, \(A\) and \(B\) of spirit and water. The ratio of spirit and water in solution \(A\) is \(3{:}4\) and \(4{:}5\) in solution \(B,\) if \(28\) litre of solution is taken from \(A\) and added to Solution \(B,\) what will be the final concentration of spirit in solution \(B.\)

1. After the addition, water in solution \(B\) is \(24 \,\text{L}\) more than spirit.

2. Initial amount of solution \(A\) is \(140 \,\text{L}\)
