so, in 25 the units place is 5 x 5 is 25
25 into 5 is equal to 125 you will notice that the five continuous to repeat in the units place
similarly in 36 6 reoccours
and, in 73 3 when continuously multipled by 73 the units digit 3,9,7,1 now you will see that the cycle continues now divide 54 by 4 you would have 2 as a reminder now the second place in the digits 9713 is holded by 9 so 9 would be in the units place
now in IIT units place we have 5 69 the sum of 5 6 and 9 is 20 The digit in the units place is hero
