@ seniors....

kindly guide me if my profile is gud enuf for the GMP program...im thinking about taking XAT-12 to apply for this program....

Xth: 79.4% CBSE
12th: 74.4 % CBSE
BE: 68.62 % in Elex and Comm

work profile: 4+ yrs of experience in Telecom domain. Working with telecom giant Nokia-Siemens Networks as RF planning and optimisation engg. No managerial exp but have a team of 4 engg under me. Have performed planning and optimisation for existing GSM and 3G netwroks. Was involved in various parameters and features testing all these years on 2G and 3G networks.No intl exp. only thing that i feel makes me my profile differ from other is my professional background as i think crowd is more from IT domain. EC revolves around sports activities including heading Football team at school level
current exp is 4.4 yrs and by mar-12 it will be 4 yr 10 mnths....so is there chance of relaxation on this part..??

To find out the last non zero digit of n!

Z(n)-> denotes the last non zero digit in expansion of n factorial
L(n)-> denotes the last digit(unit digit) of n.
Z(n)=L(4^(number of tens in n)) * Z() * Z(n%10)
[]- is the Greatest integer function.

Note:-no of tens means the quotient obtained on dividing the number by 10

So Z(80) = L(4^8 ) * Z(16) * Z(0)

Z(16) = L * Z(3) * Z(6) = 4*6*2 = 8

Z(80) = 6*8 = 8

To Calculate z(76) -
then Z(76)*7*8*9*8 = 8 (Its multiplication of all the last non zero digit of 76!,77,78,79,80)
76!*2 = 8
so last non-zero digit of 76! = 4
