If the difference between the compound and simple interests

If the difference between the compound and simple interests on a certain sum of money for 3 years at 5% per annum is ₹ 15.25, then the sum is

Given in question , Difference = C.I. - S.I. = ₹ 15.25 , Time = 3 years , Rate = 5%

Difference between C.I. and S.I for 3 years =	PR²		300 + R
	(100)²		100

⇒ 15.25 =	P × 25		5 + 300
	10000		100

⇒ 15.25 =	P × 305
	400 × 100

⇒ P =	15.25 × 400 × 100	= ₹ 2000
	305
