What is the source? IMO: C Question: Area X > Area Y? or radius x > radius y? 1. The circumference of X>Z and the circumference of Z<Y. means 2*pi*rx > 2*pi*rz, 2*pi*rz < 2*pi*ry --> No information about the relationship between rx and ry. So, Not sufficient. 2. The difference between the longest c...

Hi guys. Faced this question in gmatprep2. How to solve this question? Given equiteral triangle with side t and square with side s. If the areas of these are equal what is the ratio of t : s? 2:3 16:3 4:3^(1/2) 2:3^(1/4) 4:3^(1/4) Given that (3^1/2*t^2)/4=s^2 t^2/s^2= 4/(3^1/2) t/s= 2/(3^1/4) So op...

It says the letters can be repeated:Skywalker wrote:How to solve this one ....
OA == option E . Thanks
It also says same letters used in different order constitute to different code, So AB is different form BA
So 26+26^2+26^3=18278
