please help me to solve these questions

Answer 1

fabina borrow rs12,500 at 12%per annum for 3 years.
SI=p×r×t/100
=12,500×12×3/100
=125×12×3
=750
now ,radha borrow the. same amount for the same time at 10 % per annum.
so,A=P×(1+r/100)^3
=16637.5
CI=A-P
=16637.5-12500
=4137.5
so,radha pays more interest by rs3387.5
