Jawaban: #1: If 1st lenders we called A, and 2nd lenders we called B.So match equation for Basic loan is A+B = 20.000
Interest for A = 12%
So Total paid per annum = 100% +12% = 112%
interest for B = 14%
So total pain per annum = 100%+14% = 114%
Total interest = 2.560
So total paid = 20.000+2.560 = 22.560
If total paid A+B = 22.560
so : 112%A + 114%B = 22.560 then
A + B = 20.000
eliminated both equation
1,12A + 1,14B = 22.560 Ix1 I 1,12A + 1,14B = 22.560
A + B = 20.000 Ix 1,12 I 1,12A + 1,12B = 22.400
----------------------------------------- -
0,02B = 160
B = 160/0,02
= 8.000
A+8.000 = 20.000
A = 12.000
Conclution : Borrowed from 1st lenders : RM 12000
Borrowed from 2nd lenders : RM 8000
pls re-check each process of equation before took as final answer.
