The compound interest on Rs. 12000 for 9 months at 20% per

The compound interest on Rs. 12000 for 9 months at 20% per annum, interest being compounded quarterly is :

Given that , P = Rs. 12000 , Rate of interest =	20	= 5% per quarter , Time = 3 quarters
	4

We can find required answer with the help of given formula ,

∴ C.I. = P			1 +	R		^T	− 1
				100

C.I. = 12000			1 +	5		³	− 1
				100

C.I. = 12000			1 +	1		³	− 1
				20

C.I. = 12000			21		³	− 1
			20

C.I. = 12000		9261	− 1
		8000

C.I. = 12000		9261 - 8000
		8000

∴ C.I. =	12000 × 1261	= Rs. 1891.5
