I will mark as brainiliest ans

Answer 1

Simple Interest= Rs 189; Principal= Rs 450; Time =7/2 years. Let the rate of interest be R.
Therefore, Simple Interest= (PrincipalxTimexRate)/100
or, 189 = (450x(7/2)xR)/100
or, 189 = (450x7xR)/200
or, R = (189x200)/(450x7)
or, R = 12 %

Hence rate of interest = 12%
