when will the GIM shortlist the list?

@The_Loser two cases
1. a _ _ _ _ _ _ _ b - 26^7
2. b _ _ _ _ _ _ _ a - 26^7 since each blank/alphabet can be filled with 26 letters..
Answer---> 26^7*2!

@Logrhythm i think there would be more cases instead of 50...
49+48 , 49+47, 49+46, 49+45 and so on... will not be complemented.
similaryly, 48 + 47, 48+46 and so on....

@gnehagarg got it.. thanks..

@Logrhythm case2 - when 0 is not picked....we need to pick 2 +ve/-ve terms and a terma compensating their weight -> 50c2 ways = 1225
I didnt understand case2. Please give some example...

@gnehagarg Please exaplain how did the first staement arrive???
b+3a+c+2+1+1+a+3c+b+3+3+2+c+3b+a+1+2+3.. this one..

@gnehagarg Please explain how did the first statement arrive??

@ravi.theja Yah write... I think I am still not out of the cat 2012 trauma..

@ravi.theja Yes... 7a + b divisible by 4.
When a=0 , b =0,4,8a= 1 , b = 1,5,9a= 2, b = 2,6a= 3 , b=3,7a= 4, b = 0,4,8a= 5, b= 1,5,96 , b= 2,67, b= 3,78, b= 0,4,89, b = 1,5,910, b = 2,6..... Till a=14, b = 2
I think aise Honda cahaheyez.. Baki I m not sure..

@somnathbhatta Got it man.. thanks..!!!!
