    Answer: she invested $4000 in fund B.

    Step-by-step explanation:

    Let x represent the amount invested in fund B.

    The $2000 that she invested in fund A returned a 4% profit. It means that the profit made from fund A is

    4/100 * 2000 = 0.04 * 2000 = 80

    The amount that she invested in fund b returned B 1% profit. It means that the profit made from fund B is

    1/100 * x = 0.01x

    if both funds returned a 2% profit, it means that the profit made from both accounts is

    2/100 * (2000 + x) = 0.02 (2000 + x)

    = 40 + 0.02x

    The expression becomes

    80 + 0.01x = 40 + 0.02x

    0.02x - 0.01x = 80 - 40

    0.01x = 40

    x = 40/0.01

    x = 4000
