compounded yearly.

Given in question , Principal ( P ) = ₹ 10,000 , Rate ( r )= 10% , Time = 3.5 years

A = P		1 +	r		³	=		1 +	r/2
			100						100

A = 10,000		1 +	10		³	=		1 +	5
			100						100

A = 10,000 ×	1331	×	21
	1000		20

A = ₹ 13975.5
Compound Interest ( CI ) = Amount ( A ) - Principal ( P )
CI = ₹ (13975.5 – 10,000)
∴ CI = ₹ 3975.5
