Answer 1

Answer:

76%

Step-by-step explanation:

Ratio of boys to girls = 3x/2x

No. of boys = 3x/5x of the total people.

No. of girls = 2x/5x of total people.

Let the total number of people be 100 then,

No. of boys = 3/5 × 100 = 60.

No. of girls = 2/5 × 100 = 40.

20% of boys = 20/100 × 60 = 12.

30% of girls = 30/100 × 40 = 12.

Total no. of people who are scholarship holders = 12+12 = 25.

No. of people who do not have scholarship = 100-24 = 76.

Percentage of people who do not have scholarship = 76/100 × 100

= 76%

76% people do not have scholarship.
