Question

"At what rate
percent per annum will
₹400 amount to ₹441 in year when
interest is compounded half yearly?​

Answer 1

Step-by-step explanation:

A = p(1+(r/m))^(m×n)

m=2

n=1 year

A = 441

P = 400

441 = 400(1+r/2)²

441/400 =(1+((r/2))²

21²/20² =(1+r/2)²

(21/20)² =(1+r/2)²

(1+1/20)² =(1+r/2)²

1+1/20 =1+r/2

r/2 = 1/20

r=1/10 =0.1 =.1×100% = 10%
