1) Grab a calculator. (You wont be able to do this in your head)

2) Key in the first three digits of your phone number if ur phone number is

7 digits or else take the first 4 digits of ur number if its 8 digits.(only

land line no.)

(NOT the area code)

3) Multiply by 80

4) Add 1

5) Multiply by 250

6) Add the last four numbers of your phone number

7) Add the last four numbers of your phone number again

8 ) Subtract 250

9) Divide number by 2

Do you recognize the answer ?

:00: I got my number huh........... :?

((((xyz*80)+1)*250)+ (2*ABCD) - 250)/2

= ((((xyz*80)+1)*125)+ (ABCD) - 125)

= (xyz*80*125)+125+ ABCD - 125

= xyz * 10000 + ABCD

= xyzABCD

that is ur ph number.... :ee:

mmmm.......good.....ashok

ya..i know its simple maths.

the simillar one4000+2000=0

how....?

let a =4000, b =2000 and c =6000

a + b =c

Multiply both sides by a + b

(a + b) (a + b ) =c (a + b)

a*a + ab + ba + b*b = ca + cb

a*a + ab - ca = cb - b*b - ba

a( a + b -c) = -b(b + a - c)

so a = - b

a + b = 0

Hence 4000 + 2000 = 0............

san ithumatri varra yellame answer condupidikiravarikkum puzzle.Once if u find the answer it will become a primary school maths.

Infact for telephone puzzle, if u could do the back calculation u can find the answer.

one more primary school maths for u.hope u could find the answer for it

There were certain numbers of gold coins in a box. 7 people, need to share those coins. Without informing others, 2 of them (from 7) tried to share those coins equally. When they were sharing they found one coin was remaining. Then they decided to share equally with 3rd guy. Again they found one coin was remaining. Then they tried to share with 4th guy…….Like this up to 6 th guy ....they found one coin was remaining. Finally when they shared with 7th guy, they have not found any coin remaining.

Can u tell me how many coins were there?

me already knowssssssssss :lol: :lol: :lol:

mmmm ............i hope the coin problem is more easier than the telephone number , 4000+2000=0 problems

no assumption of A,B, X bla..bla..

:00: :00: :00:

a( a + b -c) = -b(b + a - c)

so a = - b

You can't cancel 'zero' on both sides right :think:

otherwise

0 = 0

so, 1*0 = 10000*0

so, 1 = 10000 :ahha:

so, naan 1 post potta 10000 post potta madiri
