Answer 2

The person earns ₹ 131072 on 17th day.

Step-by-step explanation:

It is given in the question that, the person earns double the next day and his first day earning is ₹ 2.

First day = ₹ 2 = $2^1$

Second day = ₹ 2 x 2 = ₹ 4 = $2^2$

Third day = ₹ 4 x 2 = ₹ 8 = $2^3$

Fourth day = ₹ 8 x 2 = ₹ 16 = $2^4$

and so on.

A pattern can be seen in the person's earning.

i.e., nth day's earning = $2^n$

So, on 17th day he earns =  ₹ $2^{17}$ = ₹ 131072
