    Answer:

    45

    Step-by-step explanation:

    According to the Question,

    • Given, Some boys and girls took part in a competition. 2/5 of the competitors were boys So 3/5 of the competitors were girls.

    And there were Total 135 competitors.

    So, the Number of Boys are 135 × (2/5) = 54 boys

    Therefore, the Number of Girls in the competition is 135-54 = 81 Girls.

    Now,

    • 1/3 of the boys were disqualified from the competition. So, 54× (1/3) = 18 boys Disqualified . the Remaining boys are 54-18 = 36 boys left in Competition.
    • Then, The number of girls more than that of boys left in competition were 81-36 = 45
