Answer 1

Answer:

I = 5%

P=1100

Step-by-step explanation:

sum of money =P

amount in three year =1265

amount in 6 years = 1430

interest in three year = 1430-1265

=165

interest per year =165/3

interest =55 per year

principle amount, P =1265-165

P= 1100

rate of interest, I =(55/1100) 100

I=5%
