The strength of a salt solution is p% if 100 ml of the solution contains p grams of salt. Each of three vessels, A, B, C contains 500 ml of salt solution of strengths 10%, 22% and 32% respectively. Now, 100 ml of the solution in vessel A is transferred to vessel B. Then, 100 ml of the solution in vessel c. Finally, 100 ml of the solution in vessel C is transferred to vessel A. The strength, in percentage, of the resulting solution in vessel A is

1.	The strength of a salt solution is p% if 100 ml of the solution contains p grams of salt. Each of three vessels, A, B, C contains 500 ml of salt solution of strengths 10%, 22% and 32% respectively. Now, 100 ml of the solution in vessel A is transferred to vessel B. Then, 100 ml of the solution in vessel c. Finally, 100 ml of the solution in vessel C is transferred to vessel A. The strength, in percentage, of the resulting solution in vessel A is
A.	15
B.	13
