RE: Quant Boosters  Geometry  Raman Sharma  Set 1
BC =1 , CA =2 so AB =rt5
using similarity in triangle ABC and ADC
we get CD= 2/rt5 and diameter of circle as 4/rt5now using tangent secant theorem
CD^2 = CE * AC
4/5 = CE *2
CE =0.4
so AE=1.6
hence 1.6/0.4 = 4 
RE: Question Bank  100 CAT level questions on Time, Speed and Distance topic
@mbatious H............D(distance).........S
Fastest one = D+D0.2 total distance
Slower one = 0.2 total distance
Time is same so
2D0.2/3 =0.2/2
4D0.4=0.6
D=1/4 or 250 mtr

@mbatious
Shikha .........48min drive......rohan...................concert
...........shikha/rohan..........................................concert
meet somewhere in between and saves 8 min drive either side
so rohan covers distance worth 40min drive in the same time shikha covers distance worth 8min drive
therefore ratio of speed = 5:1 ( rohan:shikha)
hence auto rikshaw speed = 60/5 = 12kmph
