Answer:

S.I for 5 years = 1020 - 720 = 300..... [Amount for 2 years = 720, A for 7 years = 1020, the difference gives S.I for 5 years]

S.I for each year = 300/5 = 60

Amount after 2 years = 720

S.I for 2 years = 120

Hence P = 720 - 120 = 600

S.I = P*R*T/100

60 = 600*R*1/100

R = 10%

Hence, Sum = 600 and rate% = 10
