A bottle contains a certain solution. In the bottled solution, the ratio of water to soap is 3:5, and the ratio of soap to salt is four times this ratio. The solution is poured into an open container, and after some time, the ratio of water to soap in the open container is quartered by water evaporation. At that time, what is the ratio of water to salt in the solution? Choose the correct choice from the following answers:  A) 9:100  B) 100:9  C) 12:100  D) 12:20  E) 13:100
Water:soap = 3:5   Soap:Salt=12:20   =&gt; For 12 soap, salt = 20   =&gt; For 5 Soap, salt = (20/12)*5 = 100/12=25/3   So, water:soap:salt = 3:5:25/3 = 9:15:25   9:100fter open container, water:soap:salt = 2.25:15:25   So, water:salt = 2.25:25 = 9:100   9:100NSWER:9:100
