There wont be anything on screen except questions, timer and some control buttons......u'll be given paper and pencil for rough works........... suggest u to take a powerprep before starting practise.......the real test is exact replica of this........
Let the 5 digit no: be ABCDE
this can be written as A*10000+B*1000+c*100+D*10+E
the reflection of original no: is EDCBA
this can be written as E*10000+D*1000+c*100+B*10+A
so difference ==>ABCDE - EDCBA = (A*10000+B*1000+c*100+D*10+E) - (E*10000+D*1000+c*100+B*10+A) = A*9999+B*990+C*0-D*990-E*9999
so each term in difference is divisible by 9.
Square both colums
A: 79*80*81*82 B:80*80*80*80
so by comaping we can easily say A>B

S=n/2[2 + n-1]=n(n+1)/2 ------> sum of n terms of AP with a1=1 and d=1
S1=n/2[4 + (n-1)*2]= n(n+1) = 2S ------->sum of n terms of AP with a1=2 and d=2
