A sum of 2,400 amounts to ₹3,264 in 4 years at a certain rate of simple interest. If the rate of interest is increased by 1%, the same sum in the same time would amount to

Here , Principal = 2,400 and Amount = ₹3,264
S.I. = 3264 – 2400 = ₹ 864

Rate =	S.I. × 100
	Principal × Time

Rate =	864 × 100	= 9% per annum
	2400 × 4

New rate = 10% per annum

∴ SI =	2400 × 10 × 4	= ₹ 960
	100

∴ Amount = Principal + SI = 2400 + 960 = 3360
