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%
