When will DEBTOR finish paying?

by kanha81 » Wed Mar 25, 2009 7:49 am
Hello,

2 questions:
1) if this were a PS question, how would you solve?
2) how would you try setting up the equation to find that there is not enough information, so that you can quickly move on to another question?

A certain country took $8 billion dollars loan from World Bank. Under the agreement, the debtor has to start paying a year later. If debtor pays the agreed amount on time, when will the debtor finish paying?

i) There is 5% interest on the unpaid of the loan beginning at the time of borrowing
ii) The debtor has to pay $400 million dollars, every year, deductible from what is left of preceding payment and the interest on it

best regards,

Not sure about 1 n 2 but for DS ans is C

First give you interest rate ie 5% and second gives you installment.

If interest rate is just for the first year and not clearly defined that ans is E
