x to y?

by sanju09 » Mon Feb 02, 2009 6:00 am
If x and y are positive integers, what is the ratio of x to y?

(1) x is equal to the sum of a, b, c, d, and e.

(2) y is equal to the average of a, b, c, d, and e.

IMO C

(2) y is equal to the average of a, b, c, d, and e.


From A:x=a+b+c+d+e,Not Suff

From B: Y=a+b+c+d+e/5,Not Suff

Together they are sufficient

hence C
