If the rate of interest be 4% per annum for first year,

If the rate of interest be 4% per annum for first year, 5% per annum for second year and 6% per annum for third year, then the compound interest of ₹ 10,000 for 3 years will be

Given that , R₁ = 4% , R₂ = 5% , R₃ = 6% , P = ₹ 10,000
Using the given formula ,

Amount = P

1 +

R₁

R₂

R₃

100

Amount = 10000		1 +	4			1 +	5			1 +	6
			100				100				100

Amount = 10000 ×	26	×	21	×	53	= ₹ 11575.2
	25		20		50

∴ C.I. = Amount - Principal
∴ C.I. = ₹ (11575.2 – 10000) = ₹ 1575.2
