Question

The ratio of the number of boys and girls in a school is 3 : 2. 20% of the boys and 30% of the girls
are scholarship holders. What is the percentage of students who are not scholarship holders?​

Answer 1

Step-by-step explanation:

Let there be 100 students.

Then number of boys =

5

3

×100=60

Number of girls =

5

2

×100=40

Total scholarship holders =20 % of 60 + 30 % of 40= 100

20 ×60+ 100

30 ×40 = 12+12=24

Number of students without scholarship=100−24=76

∴% of students without scholarship = 100

76 ×100=76 %

Answer 2

Answer:

Step-by-step explanation:

Let there be 100 students.

Then number of boys =

3/5×100=60

Number of girls = 2/5*100=40

Total scholarship holders =20 % of 60 + 30 % of 40=

20/100×60+ 30/100×40

= 12+12

=24

Number of students without scholarship =100−24=76

∴% of students without scholarship =

​ ​76/×100=76
