    Step-by-step explanation:

    Mean income of 99 people = $ 400

    Sum of income of 99 people = 400 * 99 = $ 39600

    Income of a woman = $ 1500

    Income of 100 people = 39600 + 1500 = $41100

    Mean of 100 people = 41100/100 = $411

    411 - 400 = $11

    Mean income increases by $11

    The new mean will be (400*99+1500) / 100=411

    The mean increased by 11.
