Given Principal P = 4000, n = 1 year. Given that the interest compounded quarterly, Compound Interest CI = 630.50.
We know that A = P + CI
= 4000 + 630.50
= 4630.5
We know that A = P(1 + r/100)^4n
4630.5 = 4000(1 + R/100 * 4)^4 * 1
4630.5 = 4000(1 + R/400)^4
4630.5/4000 = (1 + R/400)^4
1.1576 = (1 + R/400)^4
(1.1576)^1/4 = (1 + R/400)
1.0372 = (1 + R/400)
1.0372 - 1 = R/400
0.0372 = R/400
R = 14.8%.
Therefore the Rate = 14.8%.
Hope this helps!

simmi65:
bt i don't undrstnd why we take 4 two time r/100*4 and 4*1
rate to number so divided by 100 in 4 quarters so *4
and 4*1 is the power.... don't you know those rules of interest
u copied the ans it's already answered by someone i just has a look
if this is power so we don't use it to divide on other side
i think u don't know tge the rules bro
yeahhh.... im explaining you.... i checked the answer so i gave you know
hmm
anyways thnks
you don't understand ....how caan i do so big calculations on my own
