100 was the number of times no one missed mama ji in each episode.
100 were the number of net sarees Anjali di owned. All the money the production house had went into buying net sarees, this is why Arnow ji had only one suit and one pair of shoes.
100 rupees was also the budget for creating the set. Explains the bathroom, yes?
