extea money he got in 1.5 year = 3 year - 1.5 year
= 6500 - 5750 = 750 in 1.5 year
in 1 year = 750 / 1.5
= 500 in 1 year
principal = 5750 - 750
principal = 5000.
rate % = rate in 1 year / princical × 100
= 500 / 5000 ×100 = 10 %

= 6500 - 5750 = 750 in 1.5 year
in 1 year = 750 / 1.5
= 500 in 1 year
principal = 5750 - 750
principal = 5000.
rate % = rate in 1 year / princical × 100
= 500 / 5000 ×100 = 10 %
