Some boys and girls took part in a competition. 2/5 of the competitors were boys. 1/3 of the boys were disqualified from the competition. If there were 135 competitors at first, how many more girls than boys were left?

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
