  @hemant_malhotra Hello sir, To the reference of the above question, I have a doubt. It says he makes 20% profit secretly and claims to sell at the 10% loss. Then, If cost price is 100 , he makes a loss of 10 I.e. 90(S.P.) but here he SECRETLY makes a profit of 20%. So won't that be 90/1.2?

  @rajesh_balasubramanian Hello. I was just looking for an online CAT coaching and stumbled upon this. The answer seems to be 7. And i don't think 10 can be a value for B. Eg: Take the Track length as 300m. A will complete it in 50secs. And B will take 75 secs to overlap A for the first time(300/4). I can email you my solution if you'd like to give it a look. Thank you.

  @raman_sharma BC =1 , CA =2 so AB =rt5using similarity in triangle ABC and ADCwe get CD= 2/rt5 and diameter of circle as 4/rt5 now using tangent secant theoremCD^2 = CE * AC4/5 = CE *2CE =0.4so AE=1.6hence 1.6/0.4 = 4
