PROCESS

• a sum of money is paid back in two annual installment of rs.1764
• therefore the total amount paid

=(1764×2)=rs

=3528 rs

• let the sum was =p rs
• given.....t=2 years...R=5% compounded annually
• therefore according to the problem

$p(1 + \frac{5}{100} ) {}^{2} = 3528 \\ = > p = 3528 \times \frac{100 \times 100}{105 \times 105} \\ = > p = 3200 \: \:r s$

therefore the amount of money which was borrowed..was=3200Rs
