# How to solve Puzzle part-1

January 03, 2012## This page is for fun. I am writing this page so that freshers as well as seniors can think logically.I don't think freshers need to panic during 1st round of interview --the written test where the puzzle use to puzzle them.Everybody if we try to solve 5 puzzles per day and 60 days of preparation is taken, that is more than enough to crack an interview.

## Lets talk about Puzzle

**There is a merry-go-round race going on. One person says,"1/3 of those in front of me and 3/4 of those behind me, give the total number of children in the race". Then the number of children took part in the race?**

say there are x number of person in the race.

The child stating this excluding him there are (x-1) children (Here the catch is the

__Those)__so 1/3(x-1)+3/4(x-1)=x

calculating x=13

**Two trains are approaching each other at 60mph each. The length of each train is 1/6 miles. When the two locomotives (engines) meet, how many seconds will it take for them to pass each other completely?**

for passing each train completely means they need to cross themselves. So they need to travel 1/6+1/6 miles=1/3 miles

as the train approaching each other the relative speed becomes 60mph+60mph=120mph

so the required time=(1/3)miles/120 miles/hour=1/360 hour=3600/360 sec=10 sec

**There are 5 persons who have won top five places in an event in**

Olympics . one of them asks all the five

regarding their positions, they reply as

a: "i am not the last"

b: "c is in third place"

c: "E is behind A"

d: "B is in first place"

e: "D is not the first"

The persons who have won gold and silver have lied, find the

positions in order.

So as per statement the positions are-B,D,C,A,E now applying the condition gold and silver owners lied.

So rearranging again-

B,C,A,E,D

Now gold and silver owner(B.C) lied

the new sequence B,C,E,A,D

Now again B,C laying and it became a loop here

So the correct ans is B,C,E,A,D

**If i multiplied by i is me. me multiplied by multiplied by me is she. What is the value of she?**

This is more logical than a puzzle.

i*i=me

me*me=she

it is like squiring of any number must be a 2 digit number.

Those cases are 4*4=16,5*5=25,6*6=36 and so on

and again squiring of the 2 digit number must give a 3 digit number whose last digit is same as two digit number(e)

Those cases are=16*16=256 (last digit are same -6)

25*25=625(but as per first logic if i replace i with 5 so the squire must be 2 different digit other than i viz 5 so rejecting this)

36*36=1296 does not hold good for logic 1 and logic 2

So the value of she is 256 where s=2.h=5 and e=6

- . A boy is playing a game. He took totally 55 blocks and kept like placing some x number on the ground, next one less than that above those blocks like that till the topmost one is one, likexx xx x xx x x xx x x x xx x x x x xx x x x x x xx x x x x x x xx x x x x x x x xx x x x x x x x x xThe question is how many blocks are there at the base level?if you check from top most position you can get 1+2+3...n=55 (as he is having 55 blocks)we know for all n positiveso=55=> n2+n-110=0or, (n-10)*(n-11)=0or n=10 as n>0so there are 10 block in the base
