your answer is

Step-by-step explanation:

Amount after 2 years =Rs.783

Amount after 2 years =Rs.783Amount after 3 years =Rs.837

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,S.I. of 1 year =837−783=Rs.54

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,S.I. of 1 year =837−783=Rs.54⇒ S.I. of 2 years =54×2=Rs.108

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,S.I. of 1 year =837−783=Rs.54⇒ S.I. of 2 years =54×2=Rs.108Principal sum =783−108=Rs.675

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,S.I. of 1 year =837−783=Rs.54⇒ S.I. of 2 years =54×2=Rs.108Principal sum =783−108=Rs.675Therefore,

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,S.I. of 1 year =837−783=Rs.54⇒ S.I. of 2 years =54×2=Rs.108Principal sum =783−108=Rs.675Therefore,S.I.=100PRt

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,S.I. of 1 year =837−783=Rs.54⇒ S.I. of 2 years =54×2=Rs.108Principal sum =783−108=Rs.675Therefore,S.I.=100PRt⇒54=100675×R×1

Amount after 2 years =Rs.783Amount after 3 years =Rs.837Therefore,S.I. of 1 year =837−783=Rs.54⇒ S.I. of 2 years =54×2=Rs.108Principal sum =783−108=Rs.675Therefore,S.I.=100PRt⇒54=100675×R×1⇒R=67554×100=8%
