19. Solution P contains three liquids A, B and C in the ratio 2 : 3 : 5 respectively. Another solution Q contains A, B and C in the ratio 5 : 3 : 2 respectively. Solutions P and Q are mixed in the ratio 7 : 3, which gives another solution R. Now 50% volume of R is replaced by another solution having A and B in the ratio 7 : 3. The resulting solution is Z. Calculate the percentage of B in solution Z.
