hi guys this is nirmal kedia, from orissa i had attended the infy paper in Mt. Carmel College, Palace Road

i cleared the written and my intrview is on 29th at electronic city.

one important thing to be noted while filling the form is that in the column of languages known dont mention english

the puzzle question are as follows

1.A wood blog weights 30 kg. What will be the weight of the blog its thickness is doubled and length is reduced to half. (3 marks)

Answer.60 Kg.

Volume of blog = pi R^{2} L

Thickness is doubledand length is reduced by half

SoR(final) = 2R

L(final) =L/2

So the new volume willbe = pi(4R^{2})L/2

i.e. = 2pi R^{2}L

so the volume will be doubled and also the weight will be

2.Repeated question of frog climbs 3 ft and fell back 2ft in a day.

How many day will he take to climb over 30 ft well.

Answer 28.

3) Repeated

XYZ and XYZ

+AB -AB

__________ _______________

C D E F BGA

then find the value of X,Y,Z ,G

Ans.

945 945

+78 -78

____________ _____________

1023 867

X ? 9 Y - 4 Z - 5 G ? 6

4}A class has 50 students, 26 boys and 24 girls. The principal divided the students in group of 30 and 20.

He doesn?t know the exact no. of boys or girls in the group. But the proportion of no. of boys in group A is more than that of the no. ofgirls in group B.

Then tell the difference in no. of boys in group A and girls in group B.

Ans. 6.

The proportion i.e. Ab:Ag> B_{b}: BgThus Ab.Bg>Bb. Ag

Now from hit and trial method we find thatAbAgBbBg

1515119Ab. Bg16 14 10 10 Ab.Bg>Ag.Bb

Thus Ab-Bg = 6

5) given a two digit no. 15. write down a digit before it and after it so that the 4 digit no. so formed can be divisible by 15.how many such combination are possible.(3 marks)

Ans 6.1155, 4155, 7155, 3150, 6150, 9150

For divisible by 15 in decimal place either there will be 0 or 5 and the sum of the 4 digit should be divisible by 3.

6. A person has 4 enclosures of sheep. Each having different no. of sheeps. Once he counted the no. of sheep in all 4.

for the first he count 75 and write it as ~!@.

In 2^{nd} he counted 255 and write it as @~!. In third counted 183 and write it as !@~.

For the 4^{th} he write ~@! Then what is the no. of sheep in that.

I don?t know the answer of this properly but I had written 78. how plz don?t ask.

7. MissX likes cold drink very much. And in exchange of 5 empty bottles she get one cold drink. So how many drinks she can have if initially she has 77 bottles.

Answer19

With exchange of 75 bottles she get 15 drinks so now she had 17 bottles15 drinks

In exchange of 15 bottles she get 3 drink and left with 5 bottles3 drinks

In exchange of those 5 bottles she get 1 only1 drinks

---------

19 drinks

8). There are 3 friends Geoffery, Molly and Hallmann

Geoffery said

? I m 22 years old ?, ?molly is 1 year younger than me?, and ?hallmann is two year older than me?

Molly said

?Geoffery is 23 years old ?,?my and hallmann has 3 years difference in age?,

And one more statement is there

Similarly hallmann has given three statement.

If any of the two statement from each person is true find the age of them.

Answer

Geoffery: 23 molly: 22 hallmann : 25

9) it?s a repeated question of 4 girls making fruit salad using 4 fruits etc.

10) after putting the watches back in the evening before the night as the summer ends.

Mr X called his solicitor to fix a meeting in the next morning.

So find out at what time they will meet?

Answer 5 am in morning.(plz check out not sure)

Answer. 60 Kg.

Volume of blog = pi R

^{2}LThickness is doubled and length is reduced by half

So R(final) = 2R

L(final) = L/2

So the new volume will be = pi(4R

^{2})L/2i.e. = 2pi R

^{2}Lso the volume will be doubled and also the weight will be
