A Funny Mathematical Puzzle


Suppose I'd been selected for appointment to a MNC(multi national company) as an intern for a period of 3 months!
➡️So here's the conversation btw the interviewer 'nd me:
Interviewer: So..congrats.U've been selected as an intern trainee for a period of 3 months.So, let's discuss abt the salary.What u r expecting?
Me: Tnq sir.. I'll do my best here. Just pay me ₹1 on my first day! And let that double everyday, so that I'll get ₹2 on the 2nd day, ₹4 on the 3rd day, ₹8 on 4th day...and the same pattern for the 3 months!
Interviewer: Are u sure? Why u asked for such a low payment? Are u sure u want to proceed with it?
Me: Yeah sir.. Definitely... Btw, it's not a small payment for me..Pls promise me that U'll pay me as what I said now!
Interviewer: Yeah definitely! U r appointed.


➡️So question:
If I get paid like this, like ₹1 on 1st day, ₹2 on 2nd day, ₹4 on 3rd day, ₹8 on 4th day, what'll be the total amount I'll be paid at the end of 3 months(let's assume a month has 30 days)?​

Answer 1

Step-by-step explanation:

So the income is

1- Rs. 1

2- Rs. 2

3- Rs.4

4- Rs. 8

5- Rs. 16

6- Rs. 32

7- Rs. 64

8- Rs. 128

9- Rs. 256

10- Rs. 512

11- Rs. 1024

12- Rs. 2048

13- Rs. 4096

14- Rs. 8192

15- Rs. 16384

16- Rs. 32768

17- Rs. 65536

18- Rs. 131072

19- Rs. 262144

20- Rs. 524288

21- Rs. 1048576

22- Rs. 2097152

23- Rs. 4194304

24- Rs. 8388608

25- Rs. 16777216

26- Rs. 33554432

27- Rs. 67108864

28- Rs. 134217728

29- Rs. 268435456

30- Rs. 536870912

Total money of 1 month=Rs.1,07,37,41,823

That's certainly an Arab!

And money for three months= 1073741823 x 3

= 18446744073709551615

(That guy is surey intelligent!)

I prefered to calculate the long way as I am very very bored
