Question

A sum of rs.20,500 amounts to rs.25,500 in 4 years at the rate of simple interest.what is the rate of interest

Answer 1

Principal Amount (P) = Rs.20,500

Total Amount = Rs.25,500

Time (T) = 4 years

Let the rate of interest = R

Total Amount = Simple Interest + Principal Amount

Rs.25,500 = (PTR) / 100 + Rs.20,500

25,500 - 20,500 = (20,500 × 4 × R) ÷ 100

5000 = 820 R

R = 5000/820 = 6.097%

Answer 2

p = 20500

a = 25500

time = 4 years let the rate of interest be x

SI = PRT/100

SI = A-P

SI = 25500-20500 = rs 5000

5000 = 20500*R*4/100

5000 = 820*R

5000/820 = R

R =  6.09 PERCENT
