Question

in what time will the interest on a certain time of money at6% be
5/8 of it self​

Answer 1

Consider the sum = x . Given that sum of money at 6% be 5/8 of itself. Therefore, S.I = 5x / 8. T = (S.I × 100) / P × R. T = ((5x/8) ×100) / (x × 6) T = (5×100) / (8×6) T = 125/12 T =10(5/12) ( mixed fraction) That is 10 years and 5 months.
