principal =25000
let R be-R
time-4years
amount =31000
p×r×t/100=31000
25000×R×4/100=31000
25000×4×R=31000×100
100000×R=3100000
R=3100000/100000
R=31%
hope this helps you

Given - Principal, amount and time
Find - The rate of interest
Solution - The rate of interest is 6%.
The calculation of the rate of interest in this question requires two formulas.
Formula 1 - Amount = Principal + Interest.
This formula will give the amount of interest earned.
Formula 2 - Simple Interest = Principal*Rate*Time/100
Calculating interest first -
Interest = Amount - Principal
Interest = 31000 - 25000
Interest = Rupees 6000
Finding the rate of interest -
Rate of interest = 6000*100/(25000*4)
Rate of interest = 6%
Therefore, the rate of interest is 6%.
