what's the source of this problem? I suppose a man pays
not gets interest for taking a loan from the bank. This question has either been rephrased by you or is not accurate. Many aspirants like yourself will be misled by this q. For example it says,
for the first month and then says
for the rest of the month
However, if I am not mistaken and the man pays interest, the first month interest rate is d per month, while the other months' interest rate is n per month. Hence, the four months' interest must be (d+3n)/4 per month if we assume simple interest rate, i.e. flat rate. If we are restricted with compounded rate condition, then it's different answer.
In any case, this q. is **** - my opinion, as it gives no seeming benefit (sorry)

is this d+3n? I don't understand the wording here: "For the first month the interest rate is 'd' for every $1000"
Thanks
