My score in speedEx -02
Attempts: 13
Right: 11
Wrong: 2(silly mistakes)
42/100

here I am confident and have good feel of right attempting. I manage to keep accuracy very high in QA, but it goes out of my hands when it comes to reasoning. Everytime I feel I am right, 50% cases I am wrong.

Analysis of SpeedEx-02
>Geometry: 6
>Set theory:2
>Grid on Arithmetic progression etc: 4
>Maxima minima:1
>Numbers and average: 3
>Profit and loss:2
>Allegation(mixtures):2
>Relative speed: 4
>Equation: 1

my attempts:
4 from geo,
one max min,
3 numbers average,
3 grid on Arith progression,
2 set theory.
Made mistake in marking answers, so got two wrong.

PS: please don’t expect this kind of analysis for all speedEx, this paper I did earlier hence its there with me. For the rest of the SpeedEx, I thinks others should take the chance to come forward and do the analysis.

which speedex has this question?



;843737]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.

Not in speedex. But I got it. anyway, its been too long i posted the query

[monster1982]

i think most of u r still making up ypur mind to start speedEX sectional test papers.
i have done lot for thid thread. i hope more and more people will come and discuss it.

another question that i like to discuess speedEx-02 is sum of age of 10 students.
clue is find out the answer from twins.
this gives u the age od the smallest child,
its all done after that.
this is a caselet based on bit of reasoning...............

this i attempted correctly!

[monster1982]

nothing has happened yet, stilll u have enough time to prepare,
do the revesion of all the stff u have in terms of test.
if u have enrolled for two test series then u have almost got 20 to 25 full length papers.
do them once again....... do it areawise ............
it will boost your confidence and your score as well.
ABT

next question based on grid of numbers in Arith. progression is also tricky.
i thought somthing is wrong in it, data is missing........... later on i realised if i get any one common difference, either for column or for a row, i will be able to fill complete grid.
..............
rest question that i attempted were manageable.

u have not discussed one question set based on set theory,
Set theory question comes this way only. identifying them as a set theory problems is the only task u have to do, rest we know how to answer using venn diagram.
..........
cut off should be 34+ for speedEX 2.
what says others???????

[sejal_K]

i am triyng this question, but not getting the right figure, is there any short cut to this?

I got it!
To fit it on a rectangular floor, firstly we calculate, total area covered,
18^2 + 15^2 + …………1^2 = 1056.
Now write 1056 as a product of two factors: these two factors will be the side of the rectangle.
528*2 (not possible because tile of size more than 2 will not fit)
264*4(…………….same reason as above……………………………)
132*8((…………….same reason as above……………………………))
66*16(…………….same reason……………………………)
33*32 (possible)
3*96(…………….not possible……………………………)
hence only one rectangle is possible which will fit all these tiles is 33*32
now try to fit all these tiles there.
18+15 = 33 and 14+10+9 = 33, 18 + 14 = 32.
With this I got the figure as: moving from left to right and in a clock wise direction,
18….14(in top row)
18 -15 in left column
14-10-9 in right column
15- 8-9 in bottom row, rest we can easily fill.
So 1 is touching 10,9,8,7
