A man owns a rectangular plot of land with corners labeled ABCD, with AB=5 meters and BC=12 meters. He walks in a very peculiar fashion. He starts at A and walks toC. Then, he walks to the midpoint of side AD (labeled A1). Then, he walks to the midpoint of side CD (labeled C1), and then the midpoint of A1D (labeled A2). He continues in this fashion indefinitely. The total length of his path is of the form a+bc√, where a,b and c are positive integers, and c is not divisible by the square of any prime. What is the value of a+b+c?

A:{p,q,r,s,t} B:{l,m,n} Find the no of onto functions from A->B? Exp Pls
Two runners A and B start simultaneously from the two points where the circle x2 + y2 = 16 cuts the X-axis. The speeds of A and B are in the ratio 1 : 2 and they are moving in opposite directions.
If “A” started in the clockwise direction from the negative X-axis point then the co-ordinates of the point where they meet for the first time is given by.

Can someone suggest test-taking strategy for CAT second section? This is my present strategy: I start LR questions first, it takes 35-40 min.Some times I don't get answers to 1 LR set. Then I would do some of the VA questions in 30 min. Then I wouldn't have time to attempt RC. Some times I get stuck in LR set then the situation is even worse
