Question

A sum triples itself at simple interest in 8 years, when the rate of interest is​

Answer 1

Answer:

Answer: 25% is the rate of interest when principal amount triples in 8 year

Answer 2

A = P+ SI

SI = A-P

SI = 3p -p

SI = 2P

SI = PTR/100

2P = P×8×R/100

200 = 8R

R = 25

rate of interest = 25%
