The remainder obtained when 100*(9910) is divided by (100*99) + 1 is
Options:
A . 0
B . 1
C . 100
D . 9900
E . none of these
Answer: Option D : D Option (d) Go from unitary method, try for smaller numbers. Consider 10x910 = (10.9)99 (10x9)+1 Consider the remainder when 9991. go by frequency method. 9191∣∣R=9 9191∣∣R=-10 9391∣∣R= -90/91|R=+1 Therefore 9991∣∣R=1 Remainder will be only the first part of the numerator=10x9, in the case we have considered = 90 And in the question = 100x99= 9900
