Assuming Simple Interest Rate:
Find the interest for 1 year
4 years = Rs 2100
1 year = 2100 ÷ 4 = Rs 525
Find the interest rate:
Interest rate = interest/principal x 100
Interest rate = 525/6300 x 100 = 8.3%
Answer: The interest rate is 8.3%
--------------------------------------------------------------------------------------------------------------
Assuming Compounded interest rate
A = P( 1 + r)ⁿ
Find r:
6300 + 2100 = 6300 ( 1 + r)⁴
8400 = 6300( 1 + r)⁴
( 1 + r)⁴ = 64/63
1 + r = ⁴√64/63
1 + r = 1.0039
r = 0.0039
Convert to percentage:
0.0039 = 0.0039 x 100 = 3.9%
Answer: The interest rate is 3.9%
