The one of the most frequent questions in the cat exam is : Hoe to find the Unit/Last digit of a given number

here is a shortcut for this

1) we divide numbers 0-9 in three different groups:

Ist Group IInd Group IIIrd GROUP
0 4 2
1 9 3
5 7
6 8

For Ist Group:
Any power of "0" at unit place gives result 0 at unit place
Any power of "1" at unit place gives result 1 at unit place
Any power of "5" at unit place gives result 5 at unit place
Any power of "6" at unit place gives result 6 at unit place

For IInd Group:
Digit Odd power Even power
4 4 6
9 9 1

For IIIrd Group:
As such there is no specific rule to solve
As you all know a common method is to divide the power by 4 and get the remainder. Now take the unit digit of given number and raise it to the value of remainder obtained.
NOTE:
3^0 = 1 2^0 = 6
7^o = 1 8^0 = 6

I hope u will find this method easy as compared to others and apply in solving questions too
