.
F=amount at 5%; S=amount at 6%
.
F+S=100000
F=100000-S
.
0.05F+0.06S=5400
0.05(100000-S)+0.06S=5400
5000-0.05S+0.06S=5400
0.01S=400
S=40000
.
F=100000-S=100000-40000=60000
.
ANSWER: 60000 was invested at 5% and 40000 was invested at 6%.
.
CHECK:
.
0.05F+0.06S=5400
0.05(60000)+0.06(40000)=5400
3000+2400=5400
5400=5400
