Question

ojas asked for monthly pocket money from his father. his father told him , "ojas, I will give you a sum of rupees 100 every week or i will give you rupee 1 on the first day rupee 2 on the second day rupee 4 on the third day rupee 8 on the fourth day and so on. you tell me which one of the two options will you choose. after a lot of thought. ojas agreed to the second proposal . explain why

Answer 1

because take for example 1 month
ojas would get approximately 4×100=400 rupees in 1 month
whereas if he gets second way you can see that he gets as many rupees as the increasing powers of 2
i mean 2=2^1
4=2^2
8=2^8
and so on
so since the first day he got 1 rupee so on the 30th day he will have a total of approximately:
1+2+4+8+16..........2^29(since the first day he got 1 rupee si 29 days are left in the month) which is much nore than 400 rupees

Answer 2

first of all.....u think that 1st option is the best
BUT!!!!no second is the best option to get more money(I think Ojas gonna trouble his dad!!!!!!)

Lets see.
In first option, he will get 5200Rs where there are 52 weeks in a year

In second option, I think is gonna get more than one crore(I think so)

so....it shows that Ojas make himself as crorepati without doing any work
