hi guys i m new to this site i joined this forum and i recieve questions by mail but the main cause of worry for me is that i m not able to crack this questions can u tell me is this the level of questions appearing in cat
Quagmire SaysShouldnt ur first eqn be 9 = (18/x-v) - (18/x+v)? Because x-v is going to be smaller than x+v, so 18/x-v > 18/x+v
hi guys ..this is my first post at PG ...
My answer is also 20/3
me also getting as option a - 20/3
At his normal speed, Shirish can travel 18 km downstream in a fast flowing stream in 9 hours less than what he takes to travel the same distance upstream. The downstream trip would take 1 hour less than what the upstream trip would take provided he doubles his rate of rowing. What is the speed of the stream in km/hr?
(a) 20/3 (b) 8 (c) 33/4 (d) none of the foregoing
I am getting speed of stream as either zero(0) or negative(-20/3).
where x and v are speeds of Sirish and stream, respectively.
on calculating first one the relation is: x^2=v^2-4v
and then putting in second and solving.
Am i wrong somewhere??
18/(x-y)-18/(x+y) =9 =>2y/x^2-y^2=1/2(x spped of rowin,y speed of stream)
hence 2y=(x^2-y^2)/2 =(4x^2-y^2)/18
from (x^2-y^2)/2 =(4x^2-y^2)/18 we get 5x^2=8Y^2 =>5(x^2-y^2)=3y^2=>x^2-y^2=3/5*y^2
put ths vaue in eqn 2y/x^2-y^2=1/2 u get 10y/3y^2=1/2 =>y=20/3
hi me too getting the same answer, i approached with some steps like taking p=q=r=1 and then from the options was able to get the option 3). One help guys quote]
i think th question says there exists three DISTINCT real nos p,q & r.
whereas u took all of then as 1....??:
guys pls could anyone forward the quatz quetion a day mails before question #89...it will be of gr8 help to me... thnx in advance..
amar_kashyap SaysAbhi mil gaya na answer, m=-n^2...But, its lil long..let's see if we can find some different approach...
i took value of q from 1st eq..
put it in 2nd .
den d value of r frm 2nd eq n put it in 3rd one..
it was a long method.. n made mistakes too...
