(1) The average profit of 2% is one-fourth of the way from 1% to 5%.

(2) That means one-fourth of the total was invested at 5%.

(3) So the $6000 invested at 1% was three-fourths of the total.

(4) So the amount invested at 5% was $2000.

ANSWER: $2000 invested in Fund B.

CHECK:
.01(6000)+.05(2000) = 60+100 = 160
.02(8000) = 160
