This is from OG pg 290 Q 155 . Can't Understand the OG explanation. Help Reqd. Tks in advance.

Let x be the full capacity of the bucket.
Acc. to the ques if 3 ltrs is added to the bucket when it is half full(x/2), then the water increses by 1/3.

So thios means that 1/3 of the current volume of water is equal to 3 ltrs

=> (1/3)*(x/2) = 3
=> x = 18 ltrs.

Hence (ii) is sufficient.
