A sum becomes ₹ 2,916 in 2 years at 8% per annum compound interest. The simple interest at 9% per annum for 3 years on the same amount will be

Let principal be P.
Here , Amount ( A ) = ₹ 2,916 , Rate = 8% , Time = 2 years
Using the given formula ,

A = P		1 +	R		^T
			100

⇒ 2916 = P		1 +	8		²
			100

⇒ 2916 = P		27		²
		25

⇒ P =	2916 × 25 × 25	= ₹ 2500
	27 × 27

Now, Time = 3 years , Rate = 9%

∴ S.I.=	P × R × T
	100

S.I. =	2500 × 9 × 3	= ₹ 675
