SpeedEx - Sectional test papers -Career Forum

[monster1982]

hi all,
this thread is specifically for the discussion on Speed Ex we got from Career forum.
they r good. once i thought i an giving some mock paper.

i wrote speed exercise-01.
in all 36 paers are there.
i want all who are solving these papers to come forward and partcipate in this discussions.

Sugestion: dont miss out this sectinal test series.

Nice Initiative. I hope we can have some meaningful discussions related to speedex here. I haven't yet solved them yet. But plan to do so in the next month.

How do u do this
A rectangular floor has to be covered with the 9 square tiles with sides 1, 4, 7, 8, 9, 10, 14, 15, and 18 units respectively. Which of the following statement is necessarily true?
a. Square with side 1 is surrounded by squares with side 7, 8, 14, 15.
b. Square with side 1 is surrounded by squares with side 10, 8, 7, 9.
c. Square with side 1 is surrounded by squares with side 14, 15, 7, 8.
d. Square with side 1 is surrounded by squares with side 8, 9, 14, 15.
1. a only
2. b only
3. c only
4. c or d only

Someone please explain with Funda

This question is not for this thread - check out the thread on Geometry or Quant in general.

As for the Speeedx tests , well I have last years speedex - are they the same pattern or is there a marked difference in them every year.

This thread is for anything which comes under SpeedEx. No matter which Q u discuss....Geom or GK

A train approaches a tunnel AB. Inside the tunnel is a cat located at a point that is 3/8 of the distance AB measured from the entrance A. When the train whistles the cat runs. If the cat moves to the entrance of tunnel A, the train catches the cat exactly at the entrance. If the cat moves to the exit B, the train catches the cat at exactly the exit. The speed of the train is greater than the speed of the cat by what order?
(1) 3:1 (2) 4:1 (3) 5:1 (4) None of these

Relative speed equation taking distance travelled by train as X is all I have got. How do I process this problem further

You don’t need to use relative speed equation, only proportionality concept.

Let the total length of tunnel be 8. Cat is at 3 from A and 5 from B. Let the train be at distance ‘x’ from A. When cat travels 3 train travels ‘x’ . Similarly, when cat travels 5 then train travels {x+ 8 }. So
Dtrain/ Dcat = x/3 = {x+ 8 }/5 . Solving for x, we get x= 12
So’
Dtrain / Dcat = 12/3 = 4: 1
S µ D
Strain/ Scat = 12/3 = 4: 1
Hence answer is (4-1) : 1 = 3: 1

I ve started solving speedex seriously now
wat abt countdowns....wen are we going to get it?

[monster1982]

here is my performance in SpeedEx-01 (english Usage)
attempts: 13
correct :8
Score: 27/100.
i did it almost two to three weeks ago.
i am concentrating more on Reasoning.
ok, i have a question.
if i am getting 27, am i clearing cutoff for IIMs?
am i clearing cutoff for other institutes?
.
.
lets guess ourself.
i think cut off for this section would be 32 +.

iappreciate your effort,
but this is a CAT question,
bring more of SpeedEx questions, we will appreciate your effort.
and discussion will be more useful.
