Question

A class of 30 girls and 40 boys sponsored a
mango party. If 60 percent of the girls and
25 percent of the boys went on the party,
what percent of the class went on the
party?​

Answer 1

Answer:

40%

Step-by-step explanation:

Number of girls in the class = 30

60 percent of the girls = 60 x 30 / 100

= 18

Number of boys in the class = 40

25 percent of the boys = 25 x 40 / 100

= 10

=> total members went to the party = 18 + 10 = 28

but, total members in the class = 30 + 40 = 70

.•. percent of the class went on the party

= 28 x 100 / 70 = 40%
