If the compound interest on a certain sum for 2 years at 12% p.a. is Rs.1590, What would be the simple interest for same rate and same period? Options:	A) Rs.1500	B) Rs.1450	C) Rs.1550	D) Rs.1650	E) Rs.1750
Let principal be P.   Then Rs.1500mount = P + 1590   Rs.1500ccording to formula, Rs.1500mount = P*[1 + 0.12]^2   Hence, we get, P+ 1590 = P*[1.12]^2   So, P + 1590 = 1.2544P   So, 0.2544P = 1590   So, P = 6250   Hence, simple interest on â�¹6250 @ 12% for 2 years = 6250*12/100*2=
