Answer 1

Answer:

Maybe Never ..............

Answer 2

Answer:

On thirteenth day ( approx )

Step-by-step explanation:

Given,

He earns first day rs 40 and spent rs 25 on second day,

So, his earning in 2 days = 40 - 25 = 15 rupees,

That is, 15 rupees = 2 days.

1 rupee = $\frac{2}{15}$ day,

100 rupees = $\frac{2}{15}\times 100$ = $\frac{200}{15}$ ≈ 13 days,

Thus, he will earn 100 rupees on approximately thirteenth day.
