Answer 2

Answer:

6.75% or

6^3/4

Step-by-step explanation:

Let the r be the rate per cent per annum.

And Amount = Principal + C.I.

So, A = 40000 + 5582.25

= 45582.25

We have,

P= 40000

N= 2 years

R = x %

We know,

A = P(1+ r/100)^n

45582.25 = 4000(1+r/100)^2

45582.25/40000=(1+r/100)^2

(213.5/200)^2 = (1+r/100)^2

1+r/100 = 213.5/200

r/100 = 213.5/200 - 1

r/100 = 13.5/200

r = 13.5/200×100

r = 13.5/2 = 6.75

r= 135/2×10

r = 135/20

r = 27/4 = 6^3/4
