principal =4600
period =5 years
total amount= 6400
find the rate of interest percentage​

Answer 1

Step-by-step explanation:

principal = 4600

Time= 5

Amount = 6400

therefore,

A=P*(1+R/100)t

[you have to find rate]

so,

R=t(A-P) /100

R=5*(6400-4600) /100

R=5*1800/100

R=9000/100

R=90% (Ans)
