So, at the end of three yrs, the man's amount will become = ₹662. See in the above attachment for it's reference.

Answer 2

rs 662.025

Step-by-step explanation:

given :

1st year  

 principle is rs  200

$Amount = P(1+r/100)\\==> 200(1+5/100)\\==> 200(105/100)\\==> 200(1.05)\\==> 210$

2nd year

  principle is rs 200 + 210 = 410

$Amount = P(1+r/100)\\==> 410(1+5/100)\\==> 410(105/100)\\==> 410(1.05)\\==> 430.5$

3rd year

 principle is 200+430.5 = 630.5

$Amount = P(1+r/100)\\==> 430.5(1+5/100)\\==> 430.5(105/100)\\==> 430.5(1.05)\\==> 662.025$
