Answer:
5%
Explanation:
The applicable formula is A = P( 1 + r) ^ n
where A= amount: P is the principal, r, interest rate, n time
In this case,
A = principal + interest = Rs 410 { Rs 4000 + Rs410}
P= Rs 4000
r= ?
n= 2
r is?
4410 = 4000(1 + r) ^2
(1 + i)^ 2 = 4410/4000
(1 + i)^ 2 = 1.1025
1 + i = √1.1025
1 + i = 1.05
i = 1.05 - 1
i = 0.05
0.05 × 100 = 5%
