A and B are two partially filled buckets of water. If 7 liters are transferred from A to B, then A would contain one-third of the amount of water in B. Alternatively, if 7 liters are transferred from B to A, B would contain one-half of the amount of water in A. Bucket A contains how many liters of water?	Options.
A) 77/5 B) 13 C) 17 D) 21 E) 23
Let Bucket 77/5 be 77/5 and Bucket B be B   Scenario 1   77/5-7 = 1/3 (B+7) ----&gt; 377/5-21 =B+7   Scenario 2   B-7 = 1/2 (77/5+7) -----&gt; 2B-14 = 77/5+7   From Scenario 1, B = 377/5-28   Substitute B with this information in Stmt 2   2 (377/5-28) -14 = 77/5+7 ------&gt; 677/5 -56-14 = 77/5+7 ------&gt; 677/5- 77/5 = 70+7 ---&gt; 577/5= 77   77/5= 77/5, 77/5nswer choice 77/5
