Thanks a lot yaar, i did a very stupid error.Vaise we are on the wrong thread see you on the other one!!

(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).
9=18/(x+v)-18/(x-v)
and
1=18/(2x+v)-18/(2x-v)

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??

yup... its comin out to be...20/3

..i too got 20/3..

[avenger007]

hei...I can't understand the concept of no: of steps taken in an escalator..plz help me wid dis,
(speed of a person/speed of escalator) = (no: of steps on moving escalator / no: of steps of the person when escalator is off)

cld any one plz explain the concept..?

Quantitative Question # 065
------------------------------------------------------

If all palindromes (positive integers which is unchanged if you reverse the order of its digits) are written in increasing order, what is the possible number of prime values can the difference between successive palindromes take?



(1) 0 (2) 1 (3) 2 (4) 3 (5) none of these

The palindromes in increasing order are

1
2
3
...
9
11
22
33
...
99
101
111
121
131
...
191
202
212
222
...

We see that the prime difference can be either 2 or 11 - hence the answer is (3)
