(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.

I wanna know the equation of the second statement.

1) Not sufficient - Doesnt tell about the rest of the races

2) Sufficient he won 75% of his races = 30

Hence B
