hello everyone...! I have started my prep of cat from last month. I have somehow managed to cover Number system and algebra part. i am also good with di which makes me confident but the irony is that i am not being able to go through geometry,arithmetic and modern math section. the main problem i am facing is to visualize a question and go through the proper way to solve. as far as the matter is of concepts they are in my favor. 

badly need some advice..!!!!

Two straight roads R1 & R2 diverge from a point A at an angle of 120*. Ram starts walking from point A along R1 at a uniform speed of 3 km/hr. Shyam starts walking at the same time from A along R2 at a uniform speed of 2 km/hr. They continue walking for 4 hr along their respective roads and reach points B and C on R1 and R2 respectively. There is a straight line path connecting B and C. Then Ram returns to point A after walking along the line segments BC and CA. Shyam also returns to A after walking along line segments BC and CA. Their speeds remains unchanged. The time interval (in hours) between Ram's and Shyam's return to the point A is....

a. 5 route 55+26   

b. Under root 55+10  

c. Under root 55 + 13  

d. 2 Under root 55+10  

Is the question correct?

Kindly verify the path which Shyam has taken. I think it should be BC and AB for Shyam. for Ram BC and CA seems fine.Kindly verify the path which Shyam has taken. I think it should be BC and AB for Shyam. for Ram BC and CA seems fine.

What is the sum of the series 1/1+sqrt x, 1/1-x, 1/1-sqrt x,...to n terms?

Two pipes A and B can fill up a half full tank in 1.2 hours. The tank was initially empty. Pipe B was kept open for half the time required by pipe A to fill the tank by itself. Then pipe A was kept open for as much time as was required by pipe B to fill up 1/3 rd of the tank by itself. It was then found that the tank was 5/6 th full. The least time in which any of the pipes can fill the tank fully is (a) 4.8 hours (b) 4 hours (c) 3.6 hours (d) 6 hours

In a certain system(base n), if 2 and 9 are the roots of quadratic equation- x^2-px+15=0, then express (543)base6 in base n.
