In my view, this problem, if considered as a Math problem, is incomplete and therefore DEFECTIVE.
Indeed, it says that the loan is for one year and 4 months.
But this time period is not exactly integer number of quarters.
The Math does not teach us (does not teach me, at least), what to do and how to compound an amount discretely,
when the time is not integer number of compounding periods.
May be, it is written in accompanying papers; may be, there is a special agreement for it . . .
May be, there are special rules in Finance to regulate such circumstances.
But it is just out of Math; therefore, I consider this (supposedly) Math problem as defective.
