Here it goes:
A racing dog ran 40 races before retiring at age 4. How many races did he win?
(1) He won his first 30 races, all run before the age of 4.
(2) He lost 25 percent of his races before age 4, won none of his last 10 races, and won 75 percent of his races overall.
In this question, do you guys think the question asked has a good wording? It does not clarify as to till what point in the dog's life they want to know how many races did the dog win.
Do we have to assume that they are asking abt races won before retirement? (I know some of you will shout "ofcourse!")
Shouldnt the question read "How many races did he win till he retired?"
Or, am i overanalyzing a simple question?
Whenever i assume such simple things in DS word problems such as those with games won, races won, etc, it turns out normally that I should not have assumed anything though it seemed like commonsense. When i get smart and start not assuming such simple things, they dont like my answers either!
What the hell is going on with me!?

I think I agree with you but for a different reason. Why say "He lost 25 percent of his races before age 4" and then say "won 75 percent of his races overall"? From that I infer that "overall" does not equal "before age 4."
A clearer question would have had the dog die at age 4.

I disagree with that.
Racing dog is only for race. If he is retired, he won't join race any more.
Well, we can say he is "dead", which means jobless.
S(1) tells us he won his first 30 races, but we do not know how many races he won at the rest 10 races, it is insufficient.
S(2) is kind of woody. "He lost 25 percent of his races before age 4" means he won 75 percent of his races before age 4, which is equal to say "he won 75 percent of his races overall". Therefore, he won 30 races (75 percent of 40 races); It is sufficient.
Hence, the answer is B.
If you ask me why they put the sentence "won none of his last 10 races" in S(2), I will say that is a tricky thing. However, If you put S(1) and S(2) together, it will be kind of story, the racing dog won the first 30 races and lost the rest 10 races. Maybe that is why he retired, I guess.
