₹800 becomes ₹956 in 3 years at a certain rate of simple interest. If the rate of interest is increased by 4%, what amount will ₹800 become in 3 years ?

We know that ,
S.I. = Amount - Principle = 956 – 800 = Rs. 156

∴ Rate =	S.I. × 100
	Principal × Time

R =	156 × 100	= 6.5% per annum
	800 × 3

∴ New rate = 6.5 + 4 = 10.5%

∴ SI =	Principal × Time × Rate
	100

SI =	800 × 3 × 10.5	= ₹ 252
	100

∴ Amount = Principle + SI = 800 + 252 = ₹ 1052
