You can put this solution on YOUR website!
Amount @ 6.00% x
Amount @ 12.00% 2 x + 28000
Total interest earned = 27960

6.00% x+ 12.00% ( 2 x + 28000 )= 27960
6.00% x+ 12.00% * 2 x + 3360 = 27960
6.00% x+ 0.24 x + 3360 = 27960
0.06 x+ 0.24 x = 24600
0.30 x = 24600
x= 82000 Amount @ 6.00%

Amount @ 12.00% = 2 * 82000 + 28000
= 192000


CHECK
4920 + 23040 = 27960
