Answer 1

Answer:

THE ANSWER IS 75%p.a IF I'M NOT WRONG

Step-by-step explanation:

given: p=2000

         n=3yrs =36 months

        MATURITYVALUE( mv)=72000

ACCORDING TO THE FORMULA:

mv=pn+(pn(n+1)*r)/2*2400

SUBSTITUTING THE VALUES:

80325=72000+(72000*37*r)/2400

80325=72000+111r

80325-72000=111r

8325=111r

8325/111=r

:.r=75%

HENC, THE RATE IS 75%p.a
