yep, it is B.

Why not D? A says the dog won his first 30 races, all run before age of 4, and the dog retired at 4, means it did not run after 4...

And in second statement isn`t 'won 75% of his races overall' enough to answer the question...

i guess it is the subtle wording that makes the difference

the "first" 30 races and "before the age of 4".. we dont know if the dog won anymore than 30 races that before it turned 4.. if it said "before it retired at age 4" it would be more conclusive??

Dog won his first 30 races. But we don't know how many races he won between 31-40.

St1:
We are told he won all the first 30 of his 40 races, but we don't know if he lost all it's last 10 races or won some. So we can't tell how many races the dog won. Insufficient.

St2:
The dog lost 10 races. We are told he won none of his last 10, so he must have won the first 30 which = 30/40 = 75% as given in the statement. Sufficient.

Ans B

This is a really weird question.

S1: obviously insuff. Won 30 of his first races, but nothing about his last 10.

S2: won 25% before age 4. lost 10 of his last races and won 75% of his total races.

75% is enough to answer the question...

B

And if you want to check it backwards :

0.75x40 = 30 (races won)

10 races lost = 10/40 = 0.25

0.25+0.75 = 1.00 (all races)

10+30= 40 (all races)

He won his first 30 and then lost the following 10...

Good time to retire! :twisted:
