Need help with the following data sufficiency questions:
A. An integer greater than 1 that is not prime is called composite. If the two digit integer n is greater than 20, is n composite?
1. The tens digit of n is a factor of the units digit of n
2. The tens digit of n is 2
B. If the terms of a sequence are t1, t2, t3......tn what is the value of n?
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
E. In a typical rectangular coordinate system (I, II, III, IV quadrants), does line K intersect quandrant II?
1. The slope of K is -1/6
2. The Y intercept of K is -6

When the going gets tough, the tough gets going.
