CAT Quantitative Aptitude | Quant Questions 2017- PaGaLGuY

How do I solve this sum??

What's wrong with the time site?

Has anyone attempted TIME SAMCATs recently ? Not receiving percentile scores since last few days as well as the Solutions Page says that you haven't attempted the test. Can't do a proper analysis as well.


Is this because of the recent tech glitch at TIME's servers or this is an intentional step by TIME to avoid students from checking the results !


Anyone, any idea ?

Hey found a free topic-wise test platform for online CAT preparation.

http://onlinecatprep.kitabee.in/

Its actually good as there is no login procedure. Just go and give test. 

There are three runners Tom, Dick and Harry with their respective speeds of 10 km/h, 20 km/h and 30 km/h. They are initially at P and they have to run between the two points P and Q which are 10 km apart from each other. They start their race at 6 am and end at 6 pm on the same day. If they run between P and Q without any break, then how many times they will be together either at P and Q during the given time period?

15th question anyone?
