After paying the down payment, the remaining amount to be paid is :

7500-3000=4500
The 5 monthly installments are 1000 each.

So the total to be paid=1000×5=rs5000

We are to find out, at what interest rate 4500 should be accumulated in 5 months to get 5000

4500(1+i)^5/12=5000

(1+i)^5/12=1.1111

(1+i)=(1.111)^12/5

1+i=(1.111)^2.4

1+i=1.2874

i=0.2874

i=28.74%
