    The current price of the unit trust = £13,831.72

    Step-by-step explanation:

    Since it increased 7% per annum in last three years and decreased by 3% per annum before that, it implies that the unit trust decreased by 3% per annum for the first 2 years and then increased by 7% per annum for the next 3 years in the total 5 year period

    The invested after 2 years = 12,000 * (1-0.03) ^2 = £11,290.8

    This amount then grows by 7% for the next 3 years making it = 11,290.80 * (1+0.07) ^3 = £13,831.7155 = £13,831.72 (Rounded to 2 decimals)

    The current price of the unit trust = £13,831.72 (Rounded to 2 decimals)
