Assuming that the chain is not broken and the lady receives 10 paise on each post of the message, find the toal amount of money the lady receives after the 7th round of messages are posted.

Answer 1

Answer:

7812.5

Step-by-step explanation:

So on 7th round, the no. of people posted will be :

5^7 or (5*5*5*5*5*5*5)

= 78125

if she receives 10p per post.

Therefore:

10 x 78125 = 781250p = INR 7812.5
