## RaphaelFilgueiras 3 years ago jhon has a debt of \$35000 the payment day is in 16 months,he pretend to pay \$12000 at the end of 158 days,and \$13000 189 days after the first payment,how much he has to pay in payment day to discharge from debt?the interest rate is 50% in a year.(simple interest)

1. RaphaelFilgueiras

the answer in book is \$2231.95

2. experimentX

50% in year .. 50/360% per day ... perhaps this is step problem.

3. RaphaelFilgueiras

my ans is 28715.69

4. experimentX

a = 35k + 35k*0.5/360 * 158 - 12k b = a + a*0.5/360 * 189 - 13k c = b + a*0.5/360 * (16*30 - 159 - 158) ans

5. RaphaelFilgueiras

32679.9

6. RaphaelFilgueiras

i think the answ is wrong too.

7. RaphaelFilgueiras

for me that \$2231.95 is impossible

8. experimentX
9. RaphaelFilgueiras

but in second line you did not use simple interest

10. experimentX

oh ... on which line?

11. RaphaelFilgueiras

when you calculate b

12. experimentX

oh ... that's because you already paid off 12k ... if you have to pay again interest of 12k then it would be unfair .... is it like fixed deposit loan or what??
