THE Q, HAS ALREADY BEEN SOLVED.........20 DAYS BACK
 
let m and n be positive integers such that:
     
m/n = 1 - 1/2 + 1/3 - 1/4 + ... - 1/1318 + 1/1319.
 
Prove that m is divisible by 1979..
 
AWARD ............ FOR ABS. CORRECT ANS. .............. 20 RATING POINTS
 
ANSWER WOULD B REVEALED AT 10 AM TOMMOROW.
 
AND BELIEVE ME , IT WOULD TAKE A MATHEMATICAL GENIUS TO SOLVE THIS...........

............tseb eht ma i

C, THE PROBLEM LOOKS LIKE ANY OTHER ALZEBRA PROBLEM

BUT IT REQUIRES A TRICK WHICH IS VERY DIFFICULT TO VISUALISE TO UNLOCK THIS PROBLEM.......

BEST OF LUCK......................

do you want to say that m is completely divisible by 1979 i..e it will yield a whole no. on dividing m by 1979???????

m/n=1-1/2+1/3.........-1/1318+1/1319

=>1+1/2+1/3........+1/1318 +1/1319  -2(1/2+1/4......1/1318)
=>1/660 +1/661........+1/1318+/1319
=>(1/660+1/1319) +(1/661+1/1318).......combine other terms like this...
=>(1979/660x1319)+(1979/661x1318)..................
as number of terms are even all will combine.....like above in pairs...
and and and 1979 is prime.......
so proved .........

TO MR. PCDAGR8

WELL , THEN JUST SHUTUP..........

U DO NOT JUSTIFY UR SKILL AND TALENT BY POSTING AN ANSWER THAT U ALREADY HAD AN IDEA ABOUT....

THIS POST IS A TEST OF MATHEMATICAL INNOVATION OF STUDENTS WHO HAVE NOT DONE THIS PROBLEM BEFORE.........

AND U HAVE DONE NOTHING BUT SPOILED AN EXCELLENT QUESTION FOR THE OTHER USERS.........

well...
i wont....
do wat u can...
you are not the one who came to rescue me when i was stuck in this problem may be an year or something back it was my....something like mathematical innovation ....
this place is not your playschool where you can boast about your heroic deeds of rescuing dogs from public toilets or maybe solving some cool problems whose answers you got form some uber cool mexican mathematics book....
stop bullying around..and and and
SHUT UP !!

A BIT OF AN EGO U DEFINITELY HAVE ................

FIRST AND FOREMOST , MAY I KNOW WHAT I AM BOASTING ABOUT .

I JUST GAVE A Q. FOR OTHERS TO SOLVE

ON THE CONTRARY , U R TRYING TO PROVE THAT U R A MATHEMATICAL GENIUS BY NOT HAVING ENOUGH DECENCY
TO ACCEPT ALONGSIDE UR SOLUTION THAT U HAD ALREADY
ATTEMPTED THIS PROBLEM BEFORE.

AND THIS PROBLEM IS THERE IN A MEXICAN BOOK.

GET UR FACTS CLEAR AND GET LOST............
