1. The sum of n terms is 3124
2. The average (arithmatic mean) of n terms is 4

C. In the xy plane, what is the y intercept of Line L
1. The slope of line L is 3 times its y intercept
2. the x intercept of line L is -1/3

D. Of the 60 animals on a certain farm 2/3 are either pigs or cows. how many of the animals are cows?
1. The farm has more than twice as many cows are it has pigs
2. The farm has more than 12 pigs

Hi MSD_2008,

Please post each problem as a different post.

Q1 . for stmt 1 . the number could have any ten digits. But if unit digit is a factor it can not be prime. cause say digit is XY then 10X+Y is the digit.
but Y = kX hence the digit is 10X+kX always divisible by X>=2.

Sufficient. hence IMO it is A. let me know the OA.
